From 3dce38a02d6370dca690cd923619d4b00024b723 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Fri, 21 Jan 2011 16:35:18 +0000 Subject: dcbnl: make get_app handling symmetric for IEEE and CEE DCBx The IEEE get/set app handlers use generic routines and do not require the net_device to implement the dcbnl_ops routines. This patch makes it symmetric so user space and drivers do not have to handle the CEE version and IEEE DCBx versions differently. Signed-off-by: John Fastabend Signed-off-by: David S.
