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.
