From 3203df043263e1bb64d8ba970eb17b0810945504 Mon Sep 17 00:00:00 2001 From: Greg Rose Date: Tue, 27 Apr 2010 11:31:45 +0000 Subject: [PATCH] ixgbevf: Fix link speed display The ixgbevf driver would always report 10Gig speeds even when the link speed is downshifted to 1Gig. This patch fixes that problem. Signed-off-by: Greg Rose Signed-off-by: Jeff Kirsher Signed-off-by: David S.
