From 49d4b8ba97034469b941d00d5ca1e3b897394e35 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 14 Aug 2009 13:33:17 +0000 Subject: [PATCH] sky2: remove restarting workaround flag The whole restarting flag was introduced by Mike McCormack and was a temporary duct tape patch around issues with transmits inflight during restart. The problems it was covering are now fixed and the code should have been reverted. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
