Subject: [PATCH 0/3] Support IPv6 flow label based RSS
Date: Wed, 7 Feb 2024 21:43:08 -0800 [thread overview]
Message-ID: <20240208054311.3642-1-ajit.khaparde@broadcom.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1150 bytes --]
The use of 5-tuple of the source address, destination address,
source port, destination port, and the transport protocol type
may not be possible due to IP fragmentation, encryption, or
inability to parse past IPv6 extensions headers.
Flow label values can be chosen such that they can be
used as part of the input to a hash function used in a load
distribution scheme.
On supporting hardware, the 20-bit Flow Label field in the
IPv6 header can be used to perform RSS in the ingress path.
Please apply.
Example to configure IPv6 flow label based RSS:
flow create 0 ingress pattern eth / ipv6 / tcp / end actions rss types ipv6-flow-label end / end
