Thanks for the replay, I will definitely use this SIGNAL_POLL command -
I wasn't aware of the licence incompatibility with iwlib and that the
interface has been deprecated.
Anyway, I've tracked a little bit this command in the wpa_suplicant
drivers code, however I was unable to determine if the returned value
for RSSI is unified - e.g. it is guaranteed, that the value is in range
from -100 to 0 (or any arbitrary range) or if it is a raw value from
the chipset. Because according to the Wiki (and part of the iwlib)
various chipsets might operate on different scales (e.g. DBM, RCPI).
