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 v5:
RSS migration state moved to subsection and migrated
only if enabled (patch 7)
Updated sign off (patch 6)
Yuri Benditovich (7):
virtio-net: introduce RSS and hash report features
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

Suggest VIRTIO_NET_F_HASH_REPORT if specified in device
parameters.
If the VIRTIO_NET_F_HASH_REPORT is set,
the device extends configuration space. If the feature
is negotiated, the packet layout is extended to
accomodate the hash information. In this case deliver
packet's hash value and report type in virtio header
extension.
Use for configuration the same procedure as already
used for RSS. We add two fields in rss_data that
controls what the device does with the calculated hash
if rss_data.enabled is set. If field 'populate' is set
the hash is set in the packet, if field 'redirect' is
set the hash is used to decide the queue to place the
packet to.
