From dfd42d139357b23fb7629bea3bc39918a660cd4c Mon Sep 17 00:00:00 2001 From: "Robin H. Johnson" Date: Tue, 22 Feb 2011 02:54:26 +0000 Subject: net/ethtool: official interface for changing ethtool params (bug #195479) Implement a consistent interface for changing ethtool parameters, as suggested in bug 195479. All variable names are based on the long option to ethtool to set each group of parameters. Multiple entries seperated by newlines are permitted for variable values. Signed-off-by: Robin H.
