Subject: [RFC PATCH 0/3] drivers/net/virtio_net: Added RSS support.
Date: Wed, 18 Aug 2021 20:54:37 +0300	[thread overview]
Message-ID: <> (raw)

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
The completely disabling hash calculation for TCP or UDP
would disable hash calculation for IP.

RSS/RXHASH is disabled by default.

Andrew Melnychenko (3):
  drivers/net/virtio_net: Fixed vheader to use v1.
  drivers/net/virtio_net: Added basic RSS support.
  drivers/net/virtio_net: Added RSS hash report.
