... And also I dont know of any hw
that provides an interface to set hw filters on a per queue basis.

VMDq hardware would support this, no?

Am not really sure. This patch uses netdev to pass filters to hw. And I
don't see any netdev infrastructure that would support per queue

filters.

Sure. I was only saying that as far as I understand,
VMDq hardware does support this functionality.
Right, Greg?

In the case of Intel HW yes.  I'll refrain from speaking for other HW
vendors although I'm guessing it would be true in their cases also.
YMMV, caveat emptor, etc. etc.

Current Solarflare hardware supports:
- RX MAC address filters for queue selection (steering), which can be
  combined with RSS (flow hashing)
- TX MAC address filters to prevent spoofing
Multiple filters can be associated with a single queue.
