Add a define of FCOE_MTU as 2158 bytes and use FCOE_MTU when the LLD is found to support NETIF_F_FCOE_MTU. The lport->mfs is then calculated out of the 2158 FCOE_MTU. Otherwise, we stick with the netdev->mtu, i.e., LAN MTU. Also, change the notification on NETDEV_CHANGEMTU event to bypass changing mfs when LAN MTU is changed if NETIF_F_FCOE_MTU is supported.
