From 12469401bc5aebb1c1482db1253c986cf8221281 Mon Sep 17 00:00:00 2001 From: Yitchak Gertner Date: Wed, 13 Aug 2008 15:52:08 -0700 Subject: [PATCH] bnx2x: Delay in while loops Delay in while loops The delay in the loop should be after the change. This has very little effect (can save one delay) but it is the right thing to do Signed-off-by: Yitchak Gertner Signed-off-by: Eilon Greenstein Signed-off-by: David S.
