The problem of doing this is that if user starts testpmd, it is not possible to show
the configuration of the ports directly, since fwd_config_setup() has not being called
(because set_fwd_ports_list() has not being called), so it looks like portlist must be set,
but if user starts forwarding directly, then it is not necessary.
What I mean, is that by default, portlist should be all the ports.
Maybe we need to call fwd_config_setup after all the testpmd initialization.

I understand what you are doing here, but there is a problem. If you use --portmask parameter,
this function gets called when the arguments are parsed, but at that point, the ports are not configured yet,
and you get the following:

Fail: nb_rxq(1) is greater than max_rx_queues(0)
Program received signal SIGSEGV, Segmentation fault.
0x00000000004835c9 in setup_fwd_config_of_each_lcore (cfg=0xca4160 <cur_fwd_config>) at /tmp/dpdk-latest/app/test-pmd/config.c:1073

Anyway, I like the idea of moving fwd_config_setup out of fwd_config_display().
The problem is that there are other functions that should call this, such as set_fwd_lcores_list
(so, with this patch, if coremask is changed and then we call "show config fwd", we will not see any change).
Basically, all that affects the forwarding configuration should reconfigure it.
That's why I think it was decided to reconfigure the configuration when starting the forwarding or when showing the configuration.

So, we have two options:
1 - We add fwd_config_setup() in all the functions that are changing the configurations.
2 - We leave it as it was, especially with this patch, it makes more sense: http://dpdk.org/dev/patchwork/patch/13132/

Is this really necessary? I have removed it and I can quit testpmd with no problem.

Option 2 looks like the best choice here, to drop this patch in favour of patch
http://dpdk.org/dev/patchwork/patch/13132/
which is already acked.

fwd_config_setup() should be moved out of  fwd_config_display() .
The display should not setup the config again.

This is probably the best way to go.

I have changed my mind about option 2, this is doing a rename to clarify what is happening.
fwd_config_display() is renamed to fwd_config_setup_display(), it does not separate the setup from the display.

Probably we need to add that call to the commands that change number of RX/TX queues, as well.

I think this is not necessary. I would call fwd_config_setup() at startup,
so everything is setup when this is called (even if it is the first command when the prompt comes up).
I think at the end of init_config() is a good place.

Should fwd_config_setup  be added for the  --rxd and --txd  options as well?

Apologies for misleading here, but I think we should drop this patch for the moment.
It is conflicting with another patch and it is not really necessary for your changes (am I right here?),
so I would say best thing to do is to drop it and discuss if we want this change separately.

This patch is needed for the patchset and should not be dropped.

Is it conflicting with patch the following patch?

http://dpdk.org/dev/patchwork/patch/13132/

This patch is renaming fwd_config_display to fwd_config_setup_display.
It clarifies what the function is doing, but does not address the issue of separating the setup from the display.

Separating the setup from the display is resolved in my patch.

Regards,

Bernard.

Right, I thought this was only refactoring. Sorry about that!
Anyway, since fwd_config_display() is going to call only pkt_fwd_config_display() now,
it makes sense to move the code from that function to fwd_config_display().
You can send a separate patch for that, as it is only refactoring.

Thanks,
Pablo
