From 9e90c961134929678022aee0c68b16c1ed520614 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Fri, 6 Nov 2009 02:06:59 +0000 Subject: be2net: fix to set proper flow control on resume If be2 goes into suspend after a user changes the flow control settings, we are not programming them back after resume. This patch takes care of it. We now get the flow control settings before going to suspend mode and then apply them during resume. Signed-off-by: Ajit Khaparde Signed-off-by: David S.
