Unfortunately the ifconfig bundled with NetBSD does not support
"list command".

[tamp]/tmp% /sbin/ifconfig ath0 list chan
ifconfig: list: bad value

So I stole list_channels function (and required function) from FreeBSD's
ifconfig, and I got the following results.

[tamp]/usr/current/src/sbin/ifconfig# ./ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

What shall/can I do next ?

Thanks
