.Sh DESCRIPTION
The
.Nm
driver provides support for the MNT ZZ9000 graphics card and ethernet interface.
Each driver can be individually enabled or disabled. However all ZZ9000 drivers
depend on the zz9k* as the root to work.

zz* ethernet driver is considered experimental. As the MAC address is not
stored permanently in the card, it will use it's default address. This should
not impose any problem unless two ZZ9000 will be used in the same LAN. Please
configure the desired link address for the zz0 interface in rc.conf or in the
/etc/ifconfig.zz0 file, to avoid a MAC address collision.
