From 542512e4824c1cecc05478f279dccbde1d8bf97a Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Tue, 9 Jun 2009 05:39:33 +0000 Subject: [PATCH] qlge: Add support for using alternate MAC address. Extract either manufacturer or Bladecenter Open Fabric Manager (BOFM) MAC address. BOFM may indicate an alternate MAC address. This patch honors that request by extracting the MAC address from a different flash location if a flag is set. Signed-off-by: Ron Mercer Signed-off-by: David S.
