From f8d54811cb125094769704722e4eda6610339b92 Mon Sep 17 00:00:00 2001 From: Sritej Velaga Date: Fri, 1 Apr 2011 14:28:26 +0000 Subject: [PATCH] qlcnic: Use flt method to determine flash fw region Use flash layout table to get flash fw starting address and its size. If that fails, use legacy method. Signed-off-by: Sritej Velaga Signed-off-by: Anirban Chakraborty Signed-off-by: David S.
