ibmvnic: notify peers when failover and migration happen
[ Upstream commit 98025bc ] Commit 61d3e1d ("ibmvnic: Remove netdev notify for failover resets") excluded the failover case for notify call because it said netdev_notify_peers() can cause network traffic to stall or halt. Current testing does not show network traffic stall or halt because of the notify call for failover event. netdev_notify_peers may be used when a device wants to inform the rest of the network about some sort of a reconfiguration such as failover or migration. It is unnecessary to call that in other events like FATAL, NON_FATAL, CHANGE_PARAM, and TIMEOUT resets since in those scenarios the hardware does not change. If the driver must do a hard reset, it is necessary to notify peers.
