Can you look at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194855
or grab it?  It seems to be closely related.  I'm not sure if it is
useful to allow vlans to use independent MTUs.  It does not seem to make
sense for a VLAN to have a larger MTU than the trunk though (perhaps the
other direction can make sense, but maybe we should let a VLAN's MTU track
the trunk unless the VLAN's MTU is set explicitly?)
