From 61d88c6811f216de4ec26aafe24e650dc1aeb00e Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 19 May 2014 01:29:42 +0100 Subject: ethtool: Disallow ETHTOOL_SRSSH with both indir table and hash key unchanged This would be a no-op, so there is no reason to request it. This also allows conversion of the current implementations of ethtool_ops::{get,set}_rxfh_indir to ethtool_ops::{get,set}_rxfh with no change other than their parameters.
