New Revision: 215869
URL: http://svn.freebsd.org/changeset/base/215869

Log:
  MFC r215673:
  
    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).
