net: bridge: vlan: add rtm definitions and dump support
This patch adds vlan rtm definitions: - NEWVLAN: to be used for creating vlans, setting options and notifications - DELVLAN: to be used for deleting vlans - GETVLAN: used for dumping vlan information Dumping vlans which can span multiple messages is added now with basic information (vid and flags). We use nlmsg_parse() to validate the header length in order to be able to extend the message with filtering attributes later.
