From ifconfig.c I gather that
(nr->nr_rates[nr->nr_nrates - 1] & IEEE80211_RATE_VAL) / 2
is the current nominal rate in Mb/s, is that correct?
Curiously, what I observe with the RTL8192EU is that after associating,
that value starts at 1 and as transmissions are made, moves to 54 in
increasing steps, and then stays there. I guess that corroborates your
point about incorrect information being returned by the device.
Unfortunately I don't have another wifi adapter to test with.
Anyway, thanks for your help, I'll give it a rest now.
