From 8e586137e6b63af1e881b328466ab5ffbe562510 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 8 Dec 2011 19:52:37 -0500 Subject: net: make vlan ndo_vlan_rx_[add/kill]_vid return error value Let caller know the result of adding/removing vlan id to/from vlan filter. In some drivers I make those functions to just return 0. But in those where there is able to see if hw setup went correctly, return value is set appropriately.
