From 33f7d55f07ab964055d73d38774346f8d4821f00 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Mon, 11 Apr 2016 04:11:12 -0400 Subject: [PATCH] bnxt_en: Shutdown link when device is closed. Let firmware know that the driver is giving up control of the link so that it can be shutdown if no management firmware is running. Signed-off-by: Michael Chan Signed-off-by: David S.
