Maybe wrong calculation of curRate

Description

I tried to understadn the roaming mechansim, therefore I put some printks in ieeee80211_scan_sta.c function sta_roam_check. What I see was that curRate = ni->ni_rates.rs_rates[ni->ni_txrate] & IEEE80211_RATE_VAL; gives for example the 2 *rate instead of rate. For example 22 instead of 11 or 4 instead of 2. The mode I tested with was 802.11b. I don't know if this is also true for other modes, but changing roamRate with "iwpriv ath0 rate11b xx" makes more sense if it xx is not 2*xx for changing the Roaming-Level. Hope this helps you to get a better roaming.

The usage is correct but slightly unclear. The iwpriv require that you set them in units of 0.5 (as we only have integer calculations in the kernel). I have updated the names to make this slightly more clear.
