From 46c6a67495b3ec76204db800fc8d60a260f91cfe Mon Sep 17 00:00:00 2001 From: Eilon Greenstein Date: Thu, 12 Feb 2009 08:36:58 +0000 Subject: [PATCH] bnx2x: PHY lock list Some dual port PHY require HW lock since they are used by both interfaces (different driver instances). Since this list is getting longer, update a parameter at load time instead of calculating it on runtime Signed-off-by: Eilon Greenstein Signed-off-by: David S.
