How to get RTE flows working with BNXT PMD?

[Wicht, Baptiste]

Hi David, Kishore, DPDK users,

I have been able to reproduce your example with dpdk-testpmd compiled from 26.07 RC, the only “release” that is working on FreeBSD for BNXT. I could get the same results you did, thanks!

I do observe some special behavior though. In our tests, we have to use cqe_mode=1 because otherwise we do not get any unicast packets (they are all filtered). However, in dpdk-testpmd, if I use cqe_mode=1, I do not get any packets counted and the filter you have proposed cannot be create.

Is that behavior normal with cqe_mode=1?

Thanks

Baptiste

We have tried both legacy and TruFlow modes, but neither seem to be working. Legacy mode only let us do RSS for total number of queues (not a subset) and TruFlow mode ends up filtering all unicast packets.

Better to ask the bnxt maintainers directly.
Kishore? Ajit?
