I'm trying run testpmd with SR-IOV, specifically across two VFs. I see
packets being received successfully by the application but they are not
being transmitted. They are dropped with the 'TX-errors' counters
incrementing.
However, if I generate the same traffic and the DUT isn't programmed with
SR-IOV, but with testpmd just across PFs, the packets are transmitted just
fine and I don't have any TX-errors. I'm hoping someone can help me figure
out why the TX packets are being dropped in the SR-IOV case.
testpmd is running in the default "io" mode.
The DUT is a two port Intel xxv710 25G card. To simplify things, I'm not
actually using a guest, just testpmd across VFs.

Hi Bill,
This is just a guess, but perhaps the transmit drops are due to MAC
anti-spoofing checks?
You could probably prove/disprove by making the packet source MAC
match the transmit VF's MAC.

Thank you for the suggestion Lance, but that didn't correct the problem.
That being said, I would think that testpmd in "io" mode would just forward
the packets in the SR-IOV case just as it successfully does with testpmd
across the PFs (non SR-IOV) - but I could be wrong.

Solved... had to disable spoof checking:
ip link set p7p1 vf 0 spoofchk off
ip link set p7p2 vf 0 spoofchk off
Thank you!
