Message-Id: <20070605143654.23717.16259.sendpatchset@localhost.localdomain>

Subject: [RFC VLAN 03/10]: Move some device intialization code to dev->init callback
[VLAN]: Move some device intialization code to dev->init callback
Move some device initialization code to new dev->init callback to make
it shareable with netlink. Additionally this fixes a minor bug, dev->iflink
is set after registration, which causes an incorrect value in the initial
netlink message.
