From 7ec5689461989fd80f1cf82ae084f5d50a5e63ee Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 29 Jun 2013 19:23:19 +0200 Subject: alx: fix ethtool support code A number of places treated features wrongly, listing not-supported features instead of supported ones. Also, the get_drvinfo ethtool callback isn't needed, and alx_get_pauseparam can be simplified. Reported-by: Ben Hutchings Signed-off-by: Johannes Berg Signed-off-by: David S.
