From c216e8762f96b6bddf043b5788094e0b698dd4b3 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 13 Oct 2016 15:10:56 +0200 Subject: [PATCH] scsi: fcoe: set default TC priority If DCB is not enabled or compiled in we still should be setting a sane default priority. So put FCoE frames in priority class 'interactive' and FIP frames in priority class 'besteffort'. Signed-off-by: Hannes Reinecke Reviewed-by: Bart Van Assche Signed-off-by: Martin K.
