From: Qi Zhang <qi.z.zhang@intel.com>
Currently, RSS hash input is not available to AVF by ethtool, it is set
by the PF directly.
Add the RSS configure support for AVF through new virtchnl message, and
define the capability flag VIRTCHNL_VF_OFFLOAD_ADV_RSS_PF to query this
new RSS offload support.

Add the virtchnl message interface to VF, so that VF can request RSS
input set(s) based on PF's capability.
This framework allows ethtool RSS config support on the VF driver.

From: Haiyue Wang @ 2021-04-13 0:48 UTC (permalink / raw)
To: intel-wired-lan
Provides the ability to enable TCP RSS hashing by ethtool.
It gives users option of generating RSS hash based on the TCP source
and destination ports numbers, IPv4 or IPv6 source and destination
addresses.

To: intel-wired-lan
Provides the ability to enable UDP RSS hashing by ethtool.
It gives users option of generating RSS hash based on the UDP source
and destination ports numbers, IPv4 or IPv6 source and destination
addresses.

Provide the ability to enable SCTP RSS hashing by ethtool.
It gives users option of generating RSS hash based on the SCTP source
and destination ports numbers, IPv4 or IPv6 source and destination
addresses.
