Subject: [RFC PATCH 0/4] Added RSS support.

This series of RFC patches for comments and additional proposals.

Virtio-net supports "hardware" RSS with toeplitz key.
Also, it allows receiving calculated hash in vheader
that may be used with RPS.
Added ethtools callbacks to manipulate RSS.

Technically hash calculation may be set only for
SRC+DST and SRC+DST+PORTSRC+PORTDST hashflows.
The completely disabling hash calculation for TCP or UDP
would disable hash calculation for IP.

RSS/RXHASH is disabled by default.

Changes since rfc:
* code refactored
* patches reformatted
* added feature validation

Andrew Melnychenko (4):
  drivers/net/virtio_net: Fixed vheader to use v1.
  drivers/net/virtio_net: Changed mergeable buffer length calculation.
  drivers/net/virtio_net: Added basic RSS support.
  drivers/net/virtio_net: Added RSS hash report control.
