From cb4dca277694f6c53bf6daf0f5c609dda32e4656 Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Sun, 18 Mar 2012 10:33:44 +0000 Subject: [PATCH] bnx2x: consistent statistics for old FW Previously applied patch making the bnx2x statistics consistent did not apply to old FWs. This remedies it, extending the consistent behaviour to all drivers. Signed-off-by: Yuval Mintz Signed-off-by: Eilon Greenstein Reported-by: Michal Schmidt Signed-off-by: David S.
