Do you have a list of counters and configuration items that you would
need for this? Host AP exports some values through procfs
(/proc/net/hostap/wlan#), some through Linux wireless extensions
ioctls, and private ioctls (mainly, hostapd and prism2_param ioctls).

Prism2 hw/firmware statistics (tallies) are available from
/proc/net/hostap/wlan#/stats. They are updated whenever wlan card sends
an update. In addition, you might want to run 'iwpriv wlan0 inquire
61696' to force update on the stats before reading them.
