From 673483c7d3a25c43d1208bb07e3888bc5136e8cf Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Wed, 10 Nov 2010 09:29:45 +0000 Subject: qlge: Add firmware info to ethtool get regs. By default we add firmware information to ethtool get regs. Optionally firmware info can instead be sent to log. Signed-off-by: Jitendra Kalsaria Signed-off-by: Ron Mercer Signed-off-by: David S.
