From e6a9854b05c1a6af1308fe2b8c68f35abf28a3ee Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 21 Oct 2008 12:40:02 +0200 Subject: mac80211/drivers: rewrite the rate control API So after the previous changes we were still unhappy with how convoluted the API is and decided to make things simpler for everybody. This completely changes the rate control API, now taking into account 802.11n with MCS rates and more control, most drivers don't support that though.

We now can support 5 mac80211 filter flags: FIF_OTHER_BSS, FIF_ALLMULTI, FIF_PROMISC_IN_BSS, FIF_BCN_PRBRESP_PROMISC and FIF_CONTROL. This patch also avoids reconnecting if the filter flags are changed when the STA is associated. Because rx_assoc is used when full rxon is not necessary.

This enables sending of direct probes on passive channels, as long as some traffic is detected on that channel. This improves the scanning for hidden SSIDs in A-band,which is all passive channels. This patch fixes the bug no 1748. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748 2) This fix will only work with uCode version 15.28.2.8 and above. Prior versions of uCode would work only if we heard the traffic within active dwell time, which is much shorter than passive dwell time and is shorter than typical beacon periods. This patch also provids full active dwell time even if we hear traffic late in passive dwell. 3) uCode API version is incremented to 2.

For 3945 driver, it sets REPLY_RATE_SCALE command every time we connect to a new network. In this command we set for every rate the number of try and next rate. The problem mac80211 reports same mode for both B and G mode as IEEE80211_BAND_2GHZ which will cause using invalid rate other than CCK in B only network. THis patch on association will examine sta valid rate on association, if no OFDM rate in valid available rates it considers it as B only mode so we can set REPLY_RATE_SCALE command with valid B only network and only choose CCK rate in rate scaling.
