From 4b2305826ccd57a8b22d3daff543837ba27cfd43 Mon Sep 17 00:00:00 2001 From: Rasesh Mody Date: Mon, 20 May 2013 10:08:01 +0000 Subject: [PATCH] bna: Clear Driver Config Flags When HW Resets Driver configuration flags are retained across open/stop operations preventing configurations to be set in next open/stop. Setting MTU on a 1020 causes network to fail until a reboot is performed on the host. Clear the flags when configuration resets in hardware. Signed-off-by: Rasesh Mody Signed-off-by: David S.
