[PATCH v7 0/7] reference implementation of RSS and hash report |

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 v6:
Fixed a bug in patch 5 "reference implementation of hash report"
that caused the ASAN test to fail
was: n->rss_data.populate_hash = true;
fixed: n->rss_data.populate_hash = !!hash_report;
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
