From fe62d001372388abb15a324148c913f9b43722a8 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 15 May 2014 01:25:27 +0100 Subject: [PATCH] ethtool: Replace ethtool_ops::{get,set}_rxfh_indir() with {get,set}_rxfh() ETHTOOL_{G,S}RXFHINDIR and ETHTOOL_{G,S}RSSH should work for drivers regardless of whether they expose the hash key, unless you try to set a hash key for a driver that doesn't expose it.
