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().
