2009-03-16iwl3945 : fix rate scalingAbhijeet Kolekar
Patch fixes the bug 1900 at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1900 Issues: Throughput and success ratio calculations were not done properly. Number of retries were exceeding 16. Fix: Patch fixes above issues by doing window calculations inline with iwlwifi Patch adds sanity check to limit number of retries to 16.

2009-02-09iwl3945: Getting rid of the *39_rxon iwl_priv fieldsSamuel Ortiz
The iwl_rxon_cmd is really just a iwl3945_rxon_cmd structure extension. So, we can use the *_rxon fields from iwl_priv instead of the 3945 specific ones (*39_rxon). We have to then be careful when submitting REPLY_RXON host commands, since the command length as to be set according to the HW. As another precaution the reserved4 and reserved5 fields are cleared before being sent to the 3945. With the *39_rxon removal, a lot of duplicated code can be removed from the 3945 code base.

In ieee80211_sta structure there is u64 supp_rates[IEEE80211_NUM_BANDS] this is filled with all support rate from assoc_resp. If we associate with G-band AP only supp_rates of G-band will be set the other band supp_rates will be set to 0. If the user type this command this will cause mac80211 to set to new channel, mac80211 does not disassociate in setting new channel, so the active band is now A-band. then in handling the new essid mac80211 will kick in the assoc steps which involve sending disassociation frame. in this mac80211 will WARN_ON sta->supp_rates[A_BAND] == 0.

2008-12-12iwl3945: Fix rate scale for B-mode connectionAbbas, Mohamed
This patch make sure we use only CCK rate for B only network. 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.

2008-09-24mac80211: clean up rate control APIJohannes Berg
Long awaited, hard work. This patch totally cleans up the rate control API to remove the requirement to include internal headers outside of net/mac80211/. There's one internal use in the PID algorithm left for mesh networking, we'll have to figure out a way to clean that one up and decide how to do the peer link evaluation, possibly independent of the rate control algorithm or via new API. Additionally, ath9k is left using the cross-inclusion hack for now, we will add new API where necessary to make this work properly, but right now I'm not expert enough to do it. It's still off better than before. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This patch converts mac80211 and all drivers to have transmit information and status in skb->cb rather than allocating extra memory for it and copying all the data around.

This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers.

2008-03-06mac80211: RCU-ify STA info structure accessJohannes Berg
This makes access to the STA hash table/list use RCU to protect against freeing of items. However, it's not a true RCU, the copy step is missing: whenever somebody changes a STA item it is simply updated. This is an existing race condition that is now somewhat understandable. This patch also fixes the race key freeing vs. STA destruction by making sure that sta_info_destroy() is always called under RTNL and frees the key.

2008-02-29cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg
This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.
