Hi Matthew,
in near future i want to do exactly the same, if you make progress with
SR-IOV+Bridge+OpenStack please leave here some advice.

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 [1]
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...
Many thanks, that helps. Now to figure out the best approach for
shoving this
into OpenStack =)
