The testpmd_shell class is intended for sending commands to
a remote testpmd session within a test suite, and as of right now
it is missing most commands. Added commands for vlan filtering,
stripping, and insertion, as well as stopping and starting ports
during testpmd runtime.

I wonder whether, when convenient, we want to name the methods more or
less 1:1 according to the actual testpmd text command they send? I.e.
in this case should the method be named vlan_set_filter_on instead of
vlan_filter_set_on (aligns better with "vlan set filter on {port}")?
The intellisense provided by the testpmd methods is indeed a QoL
improvement for folks writing testsuites, but at the same time people
who use testpmd will always have the real commands ingrained in their
thoughts, so if we try to stay as true to those as possible, we get
the stability and intellisense and also the method names are still
intuitive.
Maybe even think tiny things like renaming the method set_forward_mode
to set_fwd_mode to align 1:1 with testpmd is good.
That's just my perspective though - I would be interested to see
whether others feel the same or not.

Worth clarifying that 4094 is the extended vlan range? Normal range is 1-1005?

So the idea is to have distinct port_stop_all() and port_stop(self,
port: int) methods? I think this is reasonable.

Could possibly be combined with tx_vlan_set() as one method which
handles both set and reset, but I think splitting them out is fine.

I generally try to name these methods in a more human-readable way, so
my intuition would lean more towards naming it something like
`set_vlan_filter_on` or `set_vlan_strip_on`. I could see how it might
make it easier for some testpmd developers, so I'm not sure which
would be better. Personally, as someone who is less familiar with all
the ins and outs of testpmd, I prefer the human-readable approach.

I think this is compelling, but to play devil's advocate, I also think
it's not just testpmd developers who might care. The broad community
of DPDK developers, who are working on DPDK features and might want to
write DTS testsuites in the future, are probably also already pretty
familiar with testpmd params. If they start using the framework, it
may be a benefit for the method names to be intuitive, so they don't
have to in essence relearn how to use testpmd just to write testsuites
for DTS. Probably not a big deal given as you say the human readable
approach is pretty intuitive too... anyways maybe this can be a
discussion point at the DTS meeting next week.
I guess people can always fall back on testpmd.send_command() if they
don't like the human readable methods...? Or would we want to ban
that?
https://doc.dpdk.org/guides/testpmd_app_ug/testpmd_funcs.html
Should testpmd class have a method for each runtime command? It's a
long list. Or just methods for the most common commands? Well, we'll
chat at the DTS meeting.

In the methods you added here, you made all of the parameters to them
optional with a default. This might make sense to allow developers to
be less verbose when calling the method with the defaults, but in the
case of things like the port ID, vlan IDs, and things of that nature I
think making these positional arguments that are required makes more
sense for readability. For example, if I were to call
testpmd.vlan_filter_set_on(), it is not clear where this vlan filter
is being modified. The default is 0 so it will set it on port 0, but
if you're just reading the test suite you wouldn't know that without
looking at the testpmd class. Verify is left as an optional parameter
because we really want to verify that the commands were successful in
all cases, but there could be an obscure reason in the future that a
developer might not really care if a command to testpmd was successful
or not.
I also noticed in most cases where you were verifying commands that
you had to check if multiple failures messages were present. Would it
be easier to check if the command was successful by querying things
like VLANs on a port or VLAN filtering status of a port instead of
trying to cover all error cases?

While it's true that the testpmd class is missing a lot of commands
that exist in testpmd, that isn't really why you are adding them.
Maybe switching this to say something like "It is missing
functionality required for verifying VLAN features on a PMD." might be
more descriptive.

This doesn't really verify that the filter was set as much as it
verifies that the port exists. Is there anything that testpmd prints
when it is successful, or possibly a way to query existing VLAN
filters on a port to see if it was set?

On all of the other verification methods the message for the error
doesn't include specifics like what port it was on or what vlan tag
failed. I am generally more in favor of including specific information
like this and many of the other testpmd methods do, so if possible I
think we should add some of this information to the other methods here
as well to make it consistent.

packing payload with "X" was some kind of convention with old DTS,
which we have adopted in other suites in new DTS too. Unless you have
a specific reason to not do this, we should probably use "X". Juraj
has also suggested that this be made a standard practice in new DTS
and document that (which is outside of the scope of this patch, just
figured I'd mention it).

We do not rely on a quiet wire (LLDP packets and such may be
happening) and we have no need for relying on a quiet wire.
I think:
If should_receive == true, we validate with "do any of the packets in
received have the expected load/data"
If should_receive == false we validate with "do none of the packets in
received have the expected load/data / do we have no packets at all"
> + received = received_packets[0]
We aren't going to use this assumption (which came from old dts) that
the packet we want to validate is the one at index 0. The scatter
suite (which is where I'm guessing this idea comes from as it is a
kind of reference testsuite currently) is being refactored to check
all the packets in received, instead of just received[0].

Why does the testsuite add testpmd methods for setting vlan ids, but
not for setting promisc mode, verbose mode, etc? I think chatting with
Jeremy about this makes sense.

I'm not sure it makes sense to default these parameters either. If we
never use the default value of -1 for vlan_id, then we might as well
make the argument positional instead of a keyword argument.

Maybe you could add some more description about what is being verified
in this method to the body of doc-string just to make things more
clear.

All of the individual arg definitions should end with periods and
start with capitalized words (the descriptions should be capitalized,
not the variable names). Additionally, the second line of the `strip`
description should be indented just to show it's a continuation line.
You can probably fit some more of this continuation on the line on the
one above as well if that's easier.

This might be easier to do with the built-in `filter` function in python:
list(filter(lambda p: hasattr(p, "load") and data in str(p.load),
received_packets))
Although what you have now is also intuitive and does the same thing
so it doesn't really matter either way.

This also uses an invalid ID but I think you could just make this

The start of this method is almost exactly the same as the start of
the one for sending a VLAN packet. Maybe a different approach could be
sending the packets in the test method, and then making this method
instead just take in a list of packets and verifying them. Or, maybe
you could instead make a different method for sending packets, and
pass what that method returns into this one. Just to make sure there
is as little duplicated code as possible.

I saw Patrick also mentioned this, but I agree, we shouldn't need to
be calling the send_command method anywhere. Maybe what we should do
just to make sure people don't use it is override the method in
TestpmdShell so that it throws an exception. That way we would enforce
the rule a little more and it'd be less confusing.
> + testpmd.vlan_filter_set_on(0)
This is also the default value for this method, so if we were going to
keep the defaults, this parameter would not be needed. However, we
still should probably make those arguments positional and leave this
as is.
> + testpmd.rx_vlan_add(1, 0)
This could also be testpmd.rx_vlan_add(1) with the defaults I believe,
but that would be more ambiguous.
> + testpmd.start()
> +

It might make more sense to define this variable above the call to
testpmd.rx_vlan_add and pass it into that function call as well. That
way it isn't hard-coded in some places and used as this variable in
others.

This part of the test method is identical to
test_vlan_receipt_no_stripping, we could instead make one method for
testing called vlan_receipt_testing(self, stripping: bool) and then
set the vlan stripping to on if the boolean is true.

This code is also identical to what is in
test_vlan_receipt_no_stripping. Maybe in that additional test method
you could also add a parameter for should_receive: bool and use that
to decide what to pass into the send_vlan_pacet_and_verify function:
def vlan_receipt_testig(self, stripping: bool, should_receive: bool)
^ As opposed to what I mentioned above with the vlan_receipt_testing function.

This method declaration isn't needed since we don't require any tear
down steps to actually clean up after the test suite.

I think maybe we could find a more descriptive name than just "vlan",
but I wasn't able to think of any that weren't overly verbose. Also,
we're just testing the basic features of a vlan in a pmd, so maybe it
makes enough sense as is.

Super nit-picky, but we should probably add a period at the end of
this description in the next version too.

Hey Dean,
Thanks for the series! One thing that caught my eye which I figured I'd
mention here since it applies to all the commits is that generally with
patches submitted to the dev mailing list the subject lines of the commits
should include the component that the commit is relevant to. In our case
with DTS, the component that you'd put at the start of the commit message
would be "dts:". So, for example, your second commit in the series would be
"dts: initial implementation for VLAN test suite". Another guideline is
they should be all lowercase other than acronyms. You can see where I got
this information from here:
https://doc.dpdk.org/guides/contributing/patches.html#commit-messages-subject-line

Ported over the promisc and verbose mode functions from
v2 of the queue start/stop suite to use for the VLAN suite.
Tweaked some of the verification methods to be
more concise, changed some docstrings to be more specific.

Ported over the promisc and verbose mode functions
from v2 of the queue start/stop suite to use for the
VLAN suite. Tweaked some of the verification methods to be
more concise, changed some docstrings to be more specific.

The subject for this commit should likely explain that this patch adds
the VLAN test suite rather than refacoring it. This sort of falls in
line with what I mentioned on the previous patch about the commit
messages being about what the entire patch adds rather than the
difference from the last version.
Additionally, I think you will find that a lot of my comments on the
previous version of this commit [1] still apply, but I'll try to point
out anything I didn't mention there in this email.

I mentioned this in more detail in the previous patch, but these
descriptions should be more about what the entire patch adds than a
change log from the previous.

The conditions should probably be stated here again briefly, and this
doc-string can go more in depth about how the testing is done than the
module which might help explain the test. You can also touch more here
on what specific cases you are testing.

It looks like you are using this payload to filter the received
packets but that might not be immediately obvious to other developers.
A comment about what this is for might help make it more clear.
Additionally, since this same filter is used later to check if you
captured the packet you are looking for, it is probably better to pull
this out into a seperate variable so it is only hard-coded in one
place.

I said in the previous version you could use filter() to shrink the
list, if you just want to find one that matches like this you could
instead use the built in function called any() in python to get a
boolean on if the packet exists or not. It does essentially the same
thing you are doing but is a little more concise.
I did something similar with the any function in this patch:

We could do the same thing here with pulling out the filtering into

Just documentation comments, the structure of the code and the
functionality look good to me.
Maybe a different subject for the commit would be more descriptive.
Something like "add methods required for VLAN test suite to
TestpmdShell". Then you can explain what methods are added in the
description.

The descriptions here should be the commit message explaining
everything that is being added, not just the diff from the previous
version. This is generally because this will end up being the
description of the commit once the final version gets merged, so the
people looking at the git history will only see the description of the
final version and have no context for what was added in the previous
versions. The same for the subject line of the commit.

If you want to have a change log associated with the commit however,
you can put comments under these 3 hyphens that won't get included in
the final commit message.

A comment on this doc-string and the one in the other vlan filter method:
This might be a little more descriptive if you explained how the port
number is being used. Maybe saying something like "number of the port
to add the filter to". Or, alternatively, you could change the first
line of this comment to say "Enable VLAN filtering for port with id
`port`". If you see the code it's clear how this port is being used,
but if you were only looking at the documentation there isn't much
information about how this port number comes into play.

Ported over the promisc and verbose mode functions
from v2 of the queue start/stop suite to use for the VLAN suite.
Tweaked some of the verification methods to be
more concise, changed some docstrings to be more specific.

The functionality all looks good to me, just a few documentation
nit-picks and a suggestion for something that I think could shorten up
one function.

Just a little documentation nit-pick, I noticed this second line is

You can inline this if-else-statement to shorten it up. Something like this:
promisc_output = self.send_command(f"set promisc {port} {'on' if on
else 'off''}")

I actually mentioned this on Nick's patch, but I think this could be
shortened. I'll copy what I said there:
The logger output and the error seem to be exactly the same here so we
should avoid duplicating them. There are a few ways to go about
combining these two cases in the conditional but I would probably just
use an f-string to conditionally look for "enabled" vs "disabled".
I wonder if this check would be easier using the dataclass for port
info since it will be a boolean inside of the dataclass rather than
just searching for a string. I think if you had a boolean for if
promisc mode was on you could use an XOR of add and is_promisc_mode
and it would have the same effect. Normally I avoid using the
dataclass if the check is simple without it just because I think it is
slightly faster that way, but if there is a good use-case for it (like
there is here) then I think we might as well use it.
I think using the testpmd.show_port_info method would make for a
cleaner approach, so I slightly favor that one.

Hey Dean, thanks for the update! I just went through and added my
comments to the patches, but most of my feedback was about
documentation and a few places where I think the classes could be
improved by refactoring a little bit and breaking some things out into
their own methods.
A few comments on the overall series however:
I think this patch should come after the patch that adds the testpmd
functions. Just because the order they appear in the series is the
order they get applied, so this patch without the patch that adds the
testpmd methods would throw a lot of errors because the methods don't

Also, could you run the formatting script
(devtools/dts-check-format.sh in the DPDK directory) on this series
when sending out the next version? I noticed it was throwing some
warnings/errors.

We probably should have these args listed in the order that they

The should_receive parameter seems like it was removed, we should
probably remove this part of the doc-string as well.

All of these test cases have the exact same start sequences (other
than one additional command for the tests that involve stripping, or
the 3 extra in the insertion case), we should find a way to pull this
out into another function that they can all call that does the testpmd
setup. Or, alternatively, you could make a decorator for these test
methods that handles all of the testpmd commands. That way, these
test_ methods only need to concern themselves with how they call the
method for sending and verifying packets and don't need to run any
testpmd commands.
I slightly prefer the decorator approach since I think that would be
cleaner than if you were to make a testpmd shell, pass it into a setup
function, and then close it after running testing, but it might be
less clear what's actually going on. Regardless, the main point of it
is having less code duplication between functions.

This VLAN tag should probably also be pulled out into a variable like
it is in other test methods, but we really should just do it once in a
separate setup method instead of changing this to match up.
