How do I set Jumbo Frames on a Gigabit NIC in FreeBSD?

...where you would use em0, bge0, or whatever the actual interface
device is.
See the manpages for the various devices, for example "man em":
Support for Jumbo Frames is provided via the interface MTU setting.
Selecting an MTU larger than 1500 bytes with the ifconfig(8)
utility con-
figures the adapter to receive and transmit Jumbo Frames. The
maximum
MTU size for Jumbo Frames is 16114.
...which usually will discuss the MTU sizes the specific devices can

What do I need to add to the rc.conf config line so that it sets up the
mtu for jumbo 16128 bytes size and sets the speed from auto to 1000? I
have this so far...
ifconfig_em0="inet x.x.x.x netmask x.x.x.x 1000baseTX"
