I've bumped into this issue several times before.  A look at the
ifconfig man page will show a way to set the interface mtu, but not
the mru.  FreeBSD has always used the mtu as the mru for the
interface, which is arguably wrong.  In every case I've encountered
this problem, the user had truly mis-configured some part of the
network and correct configuration solved the problem, so I've never
been fully convinced it needed to be fixed.
