ibmvnic: Remove netdev notify for failover resets
When handling a driver reset due to a failover of the backing server on the vios, doing the netdev_notify_peers() can cause network traffic to stall or halt. Remove the netdev notify call for failover resets. Signed-off-by: Nathan Fontenot <nfont@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
