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 WME SuperNetwork 00:25:4b:04:7c:05 2 54M 12:0 100 EPS WPA WME

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

WPA RSN

Can't seem to find the information anywhere.

Any help appreciated.
