From 634d7df89a93a52561f598bf9512f4cf72946954 Mon Sep 17 00:00:00 2001 From: Dhananjay Phadke Date: Sat, 5 Dec 2009 12:23:56 +0000 Subject: netxen: fix firmware type check Unified firmware image may not contain MN type of firmware. Driver should fall back to NOMN firmware type instead of going to flash. Signed-off-by: Dhananjay Phadke Signed-off-by: Amit Kumar Salecha Signed-off-by: David S.
