v4:
> Initialize rss_hf to IP for LPM, EM and ACL.
> Update rss_hf with l4 in parse_args for ACL.
> Fix pending checkpatch code indentation warning.
v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch errors and warnings related to non strings
greater than 80 characters.
> MACRO GET_CB_FIELD and strings greater than 80 characters
warnings are not fixed.
v1:
l3fwd-acl changes:
> Merge common init code in l3fwd-acl and l3fwd into
main.c.
> Move non-critical inline functions to l3fwd_acl.h.
> Move critial packet processing inline functions to
l3fwd_acl_scalar.h
> Move l3fwd-acl init code to l3fwd_acl.c.
> Delete l3fwd-acl directory.
l3fwd changes:
> Add '-A' as an option for ACL processing.
> Merge parsing options from l3fwd-acl and l3fwd. Retain
l3fwd-acl definitions.
> Move specific setup functions (setup_acl, setup_lpm
and setup_hash).
Testing:
> Compiled successfully for x86_64-native-linuxapp-gcc
> Tested LPM, EM and ACL basic functionality.

v4:
> No changes.
v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch warnings related to code
> MACRO GET_CB_FIELD checkpatch warning not fixed
v1:
> Remove static array configuration of Destination IP, MASK
and IF_OUT for LPM and LPM6 config.
> Add reading configuration from a file.
> Format of configuration file is as follows
#LPM route entries Dest-IP/Mask IF_OUT
L1.1.1.0/24 0
L2.1.1.0/24 1
L3.1.1.0/24 2
...
#LPM6 route entries Dest-IP/Mask IF_OUT

Hi Ravi,
Thanks to this. It seems like a good change. There are probably too many
L2/L3 variants and some of them should be merged.
Note, you will also have to merge the sample app guides in some sensible
way:

Hi Ravi,
Just a note on the structure of the commit message for this and the other
patches. The first thing to do if you are new to contributing to DPDK is
to have a read through the guidelines on "Contributing Code to DPDK":
http://dpdk.org/doc/guides/contributing/patches.html
In particular the subject line should contain the component that is being
modified. Something like:
examples/l3fwd: add config file support for exact match
Do a git log examples/l3fwd to see some other examples and have a look at
the following "Commit Messages: Subject Line" section of the above guidelines
http://dpdk.org/doc/guides/contributing/patches.html#commit-messages-subject-line
The body of the message should contain a short description of what you are changing,
at a high level, and why you are changing it. See also:
http://dpdk.org/doc/guides/contributing/patches.html#commit-messages-body
The version information in your commit message is good but that should be included
after the --- line so that it is part of the patch but not part of the commit
message.
John.

Hi,
It is probably worth putting a comment before this macro to
explain what it does. Also, it isn't clear, to me, what CB
stands for. Also, having a return in the middle of the macro
might be problematic if it is used in a function with a
different, or not, return value.

Nevermind. I see that this macro was already there and you just moved it.
So, it is not your problem. :-)

From: Ravi Kerur @ 2017-03-08 21:32 UTC (permalink / raw)
To: dev, konstantin.ananyev, bruce.richardson; +Cc: Ravi Kerur
Add config file support for v4 and v6 to build forwarding
tables.
v5:
> Changes is_bypass_line from inline to non-line.
v4:
> No changes.
v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch warnings related to code
> MACRO GET_CB_FIELD checkpatch warning not fixed
v1:
> Remove static array configuration of Destination IP, MASK
and IF_OUT for LPM and LPM6 config.
> Add reading configuration from a file.
> Format of configuration file is as follows
#LPM route entries Dest-IP/Mask IF_OUT
L1.1.1.0/24 0
L2.1.1.0/24 1
L3.1.1.0/24 2
...
#LPM6 route entries Dest-IP/Mask IF_OUT

Add config file support for v4 and v6 to build exact match
forwarding tables.
v5:
> No changes.
v4:
> No changes.
v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch warnings.
v1:
> Remove static array configuration of Dest IP,Src IP, Dest
port, Src port, Proto and IF_OUT for EM and EM6 config.
> Add reading configuration from a file.
> Format of configuration file is as follows

Hi Ravi,
There isn't any documentation team. Unfortunately. :-)
The raw documentation is in text format and is generally updated by
the developer submitting a patch.
There is already docs for l3fwd and l3fwd_acl so all that is required
is to merge them. However, you will need to take some care to remove
the duplicate sections and to make sure that the merged doc makes
sense as a whole.
See the documentation guidelines:
http://dpdk.org/doc/guides/contributing/documentation.html

Hi Ravi,
In general the commit messages don't meet the guidelines, so it is
probably worth reading through the guidelines again:
http://dpdk.org/doc/guides/contributing/patches.html
In particular have a look at the sections on the "subject line" and the
"message body".
I'll make some other comments to your patches to help you along.
Thanks,
John

Hi Ravi,
The subject line and commit message are okay. the only issue is that
the version information should be after a triple dash line so that
is doesn't appear in the commit message.
The version information is intended for reviewers so that know what
has changed since the last version. Just put the following before it:
---
>
> v5:
> > None.
>
> v4:
> > Initialize rss_hf to IP for LPM, EM and ACL.
> > Update rss_hf with l4 in parse_args for ACL.

This applies to all the commit messages.

Hi Ravi,
The subject line is fine. The body might be better saying IPv4 and IPv6 since
I initially thought you were referring to the versions below.

Same comment as before about ---.

Hi Ravi,
Same comment about Ipv4 and IPv6 and ---.
Also it is probably better to use "exact match" instead of "EM" in the
subject. It isn't as well known an acronym as LPM.

Thanks. I realized after skimming through the documents and seeing a 'doc:'
prefix for review. Some clarifications on merging 'l3fwd' and 'l3fwd-acl'
1. Instead of wholesale merger of both 'l3fwd' and 'l3fwd-acl', does it
make sense to
a. Modify 'l3fwd' document by adding ACL processing information ('-A'
cmdline) and providing a link or reference to existing 'l3fwd-acl'
documentation since nothing has changed in terms of 'l3fwd-acl'.
b. Add file read options for 'exact match' and 'longest prefix match' in
'l3fwd' documentation.
Thanks.

Merge l3fwd-acl code into l3fwd with '-A' cmdline option
to run ACL. Performance critical ACL inline functions are moved
from l3fwd-acl/main.c to l3fwd/l3fwd_acl_scalar.h.

l3fwd-acl changes:
> Merge common init code in l3fwd-acl and l3fwd into main.c.
> Move non-critical inline functions to l3fwd_acl.h.
> Move critial packet processing inline functions to
l3fwd_acl_scalar.h

l3fwd changes:
> Add '-A' as an option for ACL processing.
> Merge parsing options from l3fwd-acl and l3fwd. Retain
l3fwd-acl definitions.
> Move specific setup functions (setup_acl, setup_lpm

To: dev; +Cc: john.mcnamara, Ravi Kerur
Add support to read from config file to build ipv4 and ipv6
longest prefix match forwarding tables.
---
v6:
> Change commit message format.
v5:
> Change is_bypass_line from inline to non-line.
v4:
> No changes.
v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch warnings related to code
> MACRO GET_CB_FIELD checkpatch warning not fixed
v1:
> Remove static array configuration of Destination IP, MASK
and IF_OUT for LPM and LPM6 config.
> Add reading configuration from a file.
> Format of configuration file is as follows
#LPM route entries Dest-IP/Mask IF_OUT
L1.1.1.0/24 0
L2.1.1.0/24 1
L3.1.1.0/24 2
...
#LPM6 route entries Dest-IP/Mask IF_OUT

This work was going in the right direction.
Konstantin, as the maintainer of the ACL library,
do you think it is worth to keep this example as standalone or merged?

That would give us single l3fwd app with 3 different routing methods
(lpm, hash, acl) selectable at run-time, plus routing tables in config file.
