Format of $ ifconfigmod -v ath0 scan

Hi,

I'm interested in finding out the format of the readout from this command
on freebsd

$ ifconfigmod -v ath0 scan

SSID BSSID CHAN RATE S:N
INT CAPS
Bob 00:22:3f:33:8d:cc 1 54M 5:0
100 EP RSN<30140100000fac040100000fac04010000->

WME<dd180050f2020101020003a4000027a400->


specifically it's these bits I want to find out the format of.

WPA<dd160050f20101000050f20201000050f2->
RSN<30140100000fac040100000fac04010000->


Can't seem to find the information anywhere.

Any help appreciated.
