[BRIDGE]: netlink interface for link management
Add basic netlink support to the Ethernet bridge. Including: * dump interfaces in bridges * monitor link status changes * change state of bridge port For some demo programs see: http://developer.osdl.org/shemminger/prototypes/brnl.tar.gz These are to allow building a daemon that does alternative implementations of Spanning Tree Protocol.
