From f7185c71234434d48b96f9a0387737df1759a4af Mon Sep 17 00:00:00 2001 From: Dhananjay Phadke Date: Tue, 28 Apr 2009 15:29:11 +0000 Subject: [PATCH] netxen: fix firmware download o hold the firmware in memory across suspend, since filesystem may not be up after resuming. o reset the chip after requesting firmware, to minimize downtime for NC-SI.
