From: Yuri Benditovich
Subject: [PATCH v7 0/7] reference implementation of RSS and hash report
Date: Sun, 29 Mar 2020 18:09:46 +0300

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
