I made sure the OpenBSD man page is very clear as to what models do support
Jumbo
frames after having a few end-users ask similar questions.
The BCM5700, BCM5701, BCM5703, BCM5704, BCM5714 and BCM5780 are capable
of supporting Jumbo frames, which can be configured via the interface MTU
setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8)
utility configures the adapter to receive and transmit Jumbo frames. Us-
ing Jumbo frames can greatly improve performance for certain tasks, such
as file transfers and data streaming.
I would suggest doing the same thing for the FreeBSD man page since there are a
number of chipset revisions which do not support Jumbo's.
