Add a new address cache type called sticky. On an interface marked sticky any
address learned by the bridge is made permanent, the address will not age out
and most importantly will not migrate to another interface.
This can be used to stop mac address poisoning or clients roaming in much the
same way as static entries without the hassle of preloading the table.
