[Qemu-devel] [RFC 0/6] Virtio-net: Support RSS

[Sameeh Jubran]

From: Sameeh Jubran <address@hidden>

This series implements the Steering Mode feature which was introduced on the
virtio-dev list a while ago, which can be found here:
* https://lists.oasis-open.org/archives/virtio-dev/201805/msg00024.html

The first three patches add some infrastructure support that is used in
the following three patches.

The ebpf filter doesn't fully work yet as I'm having an issue with the
verifier which needs to be fixed.

The patches still need some love as not all of the cases have been handled
yet most of the functionality has been implemented.

Please share your thoughts and comments so I'll move forward with
sending v1 along with a fully functioning ebpf code.

Sameeh Jubran (6):
  Add bpf support to qemu
  tap: Add support for bpf ioctls
  vhost-net: Expose vhost_net_get_fd
  virtio-net: implement steering mode feature
  virtio-net: steering mode: Implement rss support
  virtio-net: rss: Add bpf filter
