From b4076d1715b8a38138db0805a85932b3b650d583 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger <shemminger@vyatta.com> Date: Thu, 30 Jul 2009 13:16:45 -0700 Subject: [PATCH] vlan: allow creating vlan when real device is not up There is no reason for the arbitrary restriction that device must be up to create a vlan. This patch was added to Vyatta kernel to resolve startup ordering issues where vlan's are created but real device was disabled. Note: the vlan already correctly inherits the operstate from real device; so if vlan is created and real device is marked down, the vlan is marked down.
