| * | mac80211/cfg80211: move iwrange handler to cfg80211Johannes Berg2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch made cfg80211 generally aware of the signal type a given hardware will give, so now it can implement SIOCGIWRANGE itself, removing more wext stuff from mac80211. Might need to be a little more parametrized once we have more hardware using cfg80211 and new hardware capabilities. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * | cfg80211: clean up signal typeJohannes Berg2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | It wasn't a good idea to make the signal type a per-BSS option, although then it is closer to the actual value. Move it to be a per-wiphy setting, update mac80211 to match. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * | cfg80211/mac80211: fill qual.qual value/adjust max_qual.qualJohannes Berg2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to various bugs in the software stack we end up having to fill qual.qual; level should be used, but wpa_supplicant doesn't properly ignore qual.qual, NM should use qual.level regardless of that because qual.qual is 0 but doesn't handle IW_QUAL_DBM right now. So fill qual.qual with the qual.level value clamped to -110..-40 dBm or just the regular 'unspecified' signal level. This requires a mac80211 change to properly announce the max_qual.qual and avg_qual.qual values. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * | mac80211: Extend the rate control API with an update callbackSujith2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AP can switch dynamically between 20/40 Mhz channel width, in which case we switch the local operating channel, but the rate control algorithm is not notified. This patch adds a new callback to indicate such changes to the RC algorithm. Currently, HT channel width change is notified, but this callback can be used to indicate any new requirements that might come up later on.

| * | mac80211: split IBSS/managed codeJohannes Berg2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch splits out the ibss code and data from managed (station) mode. The reason to do this is to better separate the state machines, and have the code be contained better so it gets easier to determine what exactly a given change will affect, that in turn makes it easier to understand. This is quite some churn, especially because I split sdata->u.sta into sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that way. I've also shuffled around some code -- null function sending is only applicable to managed interfaces so put that into that file, some other functions are needed from various places so put them into util, and also rearranged the prototypes in ieee80211_i.h accordingly.

| * | mac80211: fix aggregation for hardware with ampdu queuesJohannes Berg2009-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware with AMPDU queues currently has broken aggregation. This patch fixes it by making all A-MPDUs go over the regular AC queues, but keeping track of the hardware queues in mac80211. As a first rough version, it actually stops the AC queue for extended periods of time, which can be removed by adding buffering internal to mac80211, but is currently not a huge problem because people rarely use multiple TIDs that are in the same AC (and iwlwifi currently doesn't operate as AP). This is a short-term fix, my current medium-term plan, which I hope to execute soon as well, but am not sure can finish before .30, looks like this: 1) rework the internal queuing layer in mac80211 that we use for fragments if the driver stopped queue in the middle of a fragmented frame to be able to queue more frames at once (rather than just a single frame with its fragments) 2) instead of stopping the entire AC queue, queue up the frames in a per-station/per-TID queue during aggregation session initiation, when the session has come up take all those frames and put them onto the queue from 1) 3) push the ampdu queue layer abstraction this patch introduces in mac80211 into the driver, and remove the virtual queue stuff from mac80211 again This plan will probably also affect ath9k in that mac80211 queues the frames instead of passing them down, even when there are no ampdu queues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mac80211 currently assumes init_net for all interfaces, so really will not cope well with network namespaces, at least at this time. To change this, we would have keep track of the netns in addition to the ifindex, which is not something I want to think about right now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although most of IB and iWARP are separated from each other, there is some common code required to handle their shared CM listen port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for iWARP NICs is implemented as a separate RDS transport from IB. The code, however, is very similar to IB (it was forked, basically.) so let's keep it in one changeset. The reason for this duplicationis that despite its similarity to IB, there are a number of places where it has different semantics. iwarp zcopy support is still under development, and giving it its own sandbox ensures that IB code isn't disrupted while iwarp changes. Over time these transports will re-converge. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
