From 7614fe8888840a78ad4730d82adcc679c1af1894 Mon Sep 17 00:00:00 2001 From: Mahesh Bandewar Date: Wed, 30 Jan 2013 07:00:12 +0000 Subject: [PATCH] bnx2x: Force link UP when the interface is in LOOPBACK mode When the interface does not have carrier but when it's put into loopback mode (for tests), it does not make sense to not have the carrier. So force it! Signed-off-by: Mahesh Bandewar Acked-by: Eilon Greenstein Signed-off-by: David S.
