From: Stephen Hemminger Date: Thu, 30 Jul 2009 20:16:45 +0000 (-0700) Subject: vlan: allow creating vlan when real device is not up X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b4076d1715b8a38138db0805a85932b3b650d583;p=mv-sheeva.git 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.
