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?
