Allow for MTU sizes of up to ETHER_MAX_LEN_JUMBO (i.e. 9018) bytes to be
configured on ng_eiface ifnets. The default MTU remains unchanged at 1500 bytes. Mark ng_eiface ifnets as IFCAP_VLAN_MTU capable, so that the associated vlan(4) ifnets may use full-sized Ethernet MTUs (1500 bytes). MFC after: 3 days
