RES: [E810 Offload VLAN Stripping]

[Carlos de Souza Moraes Neto <carlosmn@weg.net>]

Hi David!

I think i messed up in some part and know it is working. I'm using testpmd to read tagged packets (IEC Sampled Values) that come to that port.




I'm using testpmd to read packets that arrive to the port.
This is the part to confirm I changed to 23.11 and revert de5da9d16430
root@SAL7:~/downloads/dpdk# git checkout v23.11
Previous HEAD position was f262f16087 version: 22.11.0
HEAD is now at eeb0605f11 version: 23.11.0
root@SAL7:~/downloads/dpdk# cat VERSION
23.11.0
root@SAL7:~/downloads/dpdk# git revert de5da9d16430

After compiling and installing it I start testpmd with

Are you testing with testpmd?
If not, please double check first with testpmd.

And describe the traffic you are testing with.

With this, I hope Intel can reproduce your issue.
