This series adds a minimal vhost-net filter support for RX.
It introduces a UAPI for VHOST_NET_SET_FILTER and a simple
SOCK_SEQPACKET message header. The kernel side keeps a filter
socket reference and routes RX packets to userspace when
it was enabled.

I wonder if a packet socket is sufficient or is this for macvtap as well?

Thanks

Tested
- vhost=on  and vhost=off
