From 6d9e5130b96daa1656966f7271e8a0928b3906c4 Mon Sep 17 00:00:00 2001 From: Nicolas Schichan Date: Sat, 9 Jul 2011 00:24:18 +0000 Subject: [PATCH] e1000: always call e1000_check_for_link() on e1000_ce4100 MACs. Interrupts about link lost or rx sequence errors are not reported by the ce4100 hardware, leading to transitions from link UP to link DOWN never being reported.
