Multi-radio node notes

To configure a radio in AP mode on NetBSD:

    sh# ifconfig xxx0 ssid blahblah chan z mediaopt hostap up

At this point either assign an IP or add it to a software bridge.  A sample
configuration:

    nwid <ssid> media auto mediaopt hostap chan 1
    nwkey <wepkey>

Sample bridging:

    create
    !brconfig $int add tlp0 add wi0 up

(there's an implicit 'ifconfig wi0' and 'ifconfig bridge0', respectively.)
