Subject: [RFC 0/3]  vhost-net: netfilter support for RX path

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.

Tested
- vhost=on  and vhost=off

Cindy Lu (3):
  uapi: vhost: add vhost-net netfilter offload API
  vhost/net: add netfilter socket support
  vhost/net: add RX netfilter offload path
