This is another update based on feedback from MST and Stephen on the last patchset. Hopefully this series can be integrated and any further enhancements can be made on top of this patchset. v8: - Made the failover managment routines more robust by updating the feature bits/other fields in the failover netdev when slave netdevs are registered/unregistered. (mst) - added support for handling
