Message

Support for VIRTIO_NET_F_RSS and VIRTIO_NET_F_HASH_REPORT
features in QEMU for reference purpose.
Implements Toeplitz hash calculation for incoming
packets according to configuration provided by driver.
Uses calculated hash for decision on receive virtqueue
and/or reports the hash in the virtio header

Changes from v7:
Patch 7.1: removed (RSS and hash report definitions)
Patch 7.2: delete configuration struct with RSS definitions
Patch 7.4: delete duplicated packet structure
Added patch 7 - adapt RSC definitions to updated header

Yuri Benditovich (7):
  virtio-net: implement RSS configuration command
  virtio-net: implement RX RSS processing
  tap: allow extended virtio header with hash info
  virtio-net: reference implementation of hash report
  vmstate.h: provide VMSTATE_VARRAY_UINT16_ALLOC macro
  virtio-net: add migration support for RSS and hash report
  virtio-net: align RSC fields with updated virtio-net header
