From 5e7565930524410f097f5b04f8aba663089a6ffc Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 25 Nov 2009 07:54:54 +0000 Subject: vlan: support "loose binding" to the underlying network device Currently the UP/DOWN state of VLANs is synchronized to the state of the underlying device, meaning all VLANs are set down once the underlying device is set down. This causes all routes to the VLAN devices to vanish. Add a flag to specify a "loose binding" mode, in which only the operstate is transfered, but the VLAN device state is independant.
