Marko Zec abe80e1272 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).
