It would be a bit hard for bridge based promiscuous environment to work OOB
for one of the functions (PF or VF) in SRIOV, this is generic issue,
and not related
to specific vendor.

You need to use the bridge (8) tool (part of iproute2) and add the P.V
VM MACs to
the PF interface as "self" see some slides  (21/22/23) from netdev 0.1
that deal with that
https://netdev01.org/docs/netdev_tutorial_bridge_makita_150213.pdf

Or.

It also possible to mark one bridge port (the PF) as non-promiscuous,
but I haven't
played with that myself yet (slide 32), so can't just send you doing it...
