3df7fad0cf 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.

3fab76690c Bring in support for the Rapid Spanning Tree Protocol (802.1w).
RSTP provides faster spanning tree convergence, the protocol will exchange
information with neighboring switches to quickly transition to forwarding
without creating loops. The code will default to RSTP mode but will downgrade
any port connected to a legacy STP network so is fully backward compatible.
