New Revision: 200558
URL: http://svn.freebsd.org/changeset/base/200558

Log:
  Tell upper layer vge(4) supports long frames. This should be done
  after ether_ifattach(), as ether_ifattach() initializes it with
  ETHER_HDR_LEN.
  While I'm here remove setting if_mtu, it's already handled in
  ether_ifattach().
