From 7b332244a63dc1f408fd2ebb2636d58ac69a4916 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 1 Jun 2007 09:43:59 -0700 Subject: [PATCH] 8139cp: fix VLAN unregistration The 8139cp driver did VLAN unregistration incorrectly. It disables VLAN completely when the first VID is unregistered. It should instead disable VLAN when the group is unregistered by calling cp_vlan_rx_register with a NULL grp.
