[dpdk-dev] [PATCH] Virtio TX: reverting a small change causing Virtio standard TX broken

[Vipul Ashri]

Virtio Standard TX broken : Reverting a small change added few months back which has caused breakage in Virtio Standard TX path.

During basic ping Tx/Rx testing of net_virtio pmd driver using standard Tx path, We saw TX is broken since anomaly code added by below patch once submitted

First, your commit title and commit message have several problems:
1. Title should be: net/virtio: TITLE_OF_YOUR_COMMIT. As your patch is a
fix patch, your title maybe 'fix XXXX'.
2. Title and description too long, should be less or equal than around 75 chars
per line
3. Seems the link you attached is the bad commit you want to fix. Please use
this way to point it out: add 'Fixes: BAD_COMMIT_ID ("BAD_COMMIT_TITLE")' under
the commit msg.

For all above problems, please see previous git log for reference.

And for the patch content, what is the exact issue you met? I've been told that
the deleted lines were for some CI errors. Besides, better keep the '\' aligned.

Also, please cc to related maintainers in your v2 because otherwise it'll be hard
for them to see your patch.(use get-maintainer.sh to know them)

Thanks!
Chenbo

The title is not right. As I told you,
please put 'Fixes: 57f90f894588 ("net/virtio: reuse packed ring functions")'
between the commit message and your 'Signed-off-by'. Note that the prefix
should be 'Fixes' and the commit id length is 12.

Could you refer to other commit with 'Fixes' to make it right?

Could you tell me what problem you solved? You just describe the result but
not the root cause.

Thanks!
Chenbo

[dpdk-dev] [PATCH v2] Fixes: 57f90f894588("net/virtio: reuse packed ring functions")

[Vipul Ashri]

Problem - Standard Tx packets are not going out and found broken
 due to cleanup malfunctioning whereever below mentioned macro is
 used.

RootCause - Here inside Macro 'ASSIGN_UNLESS_EQUAL(var, val)'
 assignment to 'var' argument passed is always failing as assignment
 done using 'var_' having local scope only.

I understand now. Your patch makes sense. But your commit title/msg is still
wrong. An example commit message should be (you could use this):

net/virtio: fix wrong variable assignment in helper macro

Inside Macro ASSIGN_UNLESS_EQUAL(var, val), assignment to var is always failing
as assignment done using var_ having local scope only. This leads to TX packets
not going out and found broken due to cleanup malfunctioning. This patch fixes
the wrong variable assignment.

[dpdk-dev] [PATCH v3] net/virtio: fix wrong variable assignment in helper macro

[Vipul Ashri]

Inside Macro ASSIGN_UNLESS_EQUAL(var, val), assignment to var is always
failing as assignment done using var_ having local scope only.
This leads to TX packets not going out and found broken due to cleanup
malfunctioning. This patch fixes the wrong variable assignment.

Hi All

I tried twice uploading this same patch but it is still not listed under http://patches.dpdk.org/project/dpdk/list/.
Please let me know if I am missing something and required to do some additional steps to submit my patch.

Thanks to Xia  for reviewing this code!

Your patches were hold in the administration queue because of that, I have
released them and cleaned up the patchwork (since there were double of some
