1) There was a bug which limited the total number of network interfaces
   to 16 (an array dimensioned to 16 elements).  I'm not sure if/when the
   fix was MFC'd.  (I can't find the relevant commit off-hand).

>/sbin/ifconfig vlan0 inet 10.10.10.10 netmask 255.255.255.0

These two lines can be combined.

2) You need to do an "ifconfig xl1 up" first.  You don't need to
   specify an IP address/netmask/etc, but can/should specify physical
   characteristics (10/100, half/full duplex etc).
