Subject: [RFC PATCH net-next 0/2] sfc: enable 4-tuple UDP RSS hashing
Date: Tue, 27 Sep 2016 17:32:19 +0100 [thread overview]
Message-ID: <cc07d60a-189c-8475-ecb3-b612ff13bd5a@solarflare.com> (raw)
EF10 based NICs have configurable RSS hash fields, and can be made to take the
ports into the hash on UDP (they already do so for TCP). This patch series
enables this, in order to improve spreading of UDP traffic.
Patch 2/2, which updates the ETHTOOL_GRXFH handling to report the new RSS hash
settings, uses a somewhat unorthodox construct to control fall-through flow in
a switch statement - is this acceptable style?

sfc: report 4-tuple UDP hashing to ethtool, if it's enabled
