Could you please explain the SR-IOV configuration that you are trying out?
Please provide all the details.

Thanks,
Harish

I ultimately want to run dpdk in a VM with PCI pass through on SR-IOV ports. I have had no luck there so I thought I would start with DPDK on bare metal using the PFs.

I am using Ubuntu 14.04.3 with the Ubuntu 3.19.0-31 kernel and dpdk from the dpdk.org master branch (d739ba4c6abf00eeeb680ab4e9540899182ea74d).

If running dpdk with the PFs on bare metal fails, I am not surprised that running with SR-IOV fails.

See the two patches I have posted to this list recently w/respect to the
bnx2x.  At this point, I have a VF on a 57810 working in the TX direction.
I am unable to figure out what is wrong with the RX direction though.

The rx packet counters increment but I don't seem to get packet delivery.

There is probably a minor issue with bnx2x_fill_accept_flags() being
used in both the PF and VF drivers when setting the rx filter but fixing
that didn't seem to help.

At this point it is a long slog comparing the linux driver to the
PMD driver.

[dpdk-dev] Status of bnx2x pmd?

[Mussar, Gary]

I have been attempting to build testpmd with the bnx2x pmd enabled to try and talk through a bcm57810 10G NIC card. I have tried using SR-IOV VFs and I have tried using the PFs. Neither seem to be able to be properly initialized in testpmd and/or testpmd aborts.

Is this PMD actually usable or is it trash?
