...nd listen for slave events. 2. 'net_failover' driver that provides APIs to create/destroy upper netdev and supports 3-netdev model used by virtio-net. - Added documentation v10: - fix net_failover_open() to update failover CARRIER correctly based on standby and primary states. - fix net_failover_handle_frame() to handle frames received on standby when primary is present. - replace netdev_upper_dev_link with netdev_master_upper_dev_link and handle lower dev state changes. - fix net_failver_create() and net_failover_register() interfaces to use ERR_PTR and avoid arg ** - disable setting mac address...

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
