Now minimal virtual header length is may include the entire v1 header
if the hash report were populated.

Added features for RSS and RSS hash report.
Added initialization, RXHASH feature and ethtool ops.
By default RSS/RXHASH is disabled.
Added ethtools ops to set key and indirection table.

Added set_hash for skb.
Also added hashflow set/get callbacks.
Virtio RSS "IPv6 extensions" hashes disabled.
Also, disabling RXH_IP_SRC/DST for TCP would disable then for UDP.
TCP and UDP supports only:
ethtool -U eth0 rx-flow-hash tcp4 sd
RXH_IP_SRC + RXH_IP_DST
ethtool -U eth0 rx-flow-hash tc
The header v1 provides additional info about RSS.
Added changes to computing proper header length.
In the next patches, the header may contain RSS hash info
for the hash population.

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+
