* mac80211: rate control status only for controlled packetsJohannes Berg2009-03-271-1/+3
| | | | | | | | | This patch changes mac80211 to not notify the rate control algorithm's tx_status() method when reporting status for a packet that didn't go through the rate control algorithm's get_rate() method.

* mac80211: Extend the rate control API with an update callbackSujith2009-02-271-0/+12
| | | | | | | | | | | | | | 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: remove rate_control_clearJohannes Berg2008-10-311-6/+0
| | | | | | | | | | "Clearing" the rate control algorithm is pointless, none of the algorithms actually uses this operation and it's not even invoked properly for all channel switching. Also, there's no need to since rate control algorithms work per station. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211/drivers: rewrite the rate control APIJohannes Berg2008-10-311-3/+2
| | | | | | | | | | | | 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.

* mac80211: clean up rate control APIJohannes Berg2008-09-241-76/+26
| | | | | | | | | | | | | | | | | | 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>
* mac80211: share sta->supp_ratesJohannes Berg2008-09-151-1/+1

* build algorithms into the mac80211 moduleAdrian Bunk2008-06-301-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old infrastructure was: - the default algorithm is built into mac80211 - other algorithms get into their own modules The implementation of this complicated scheme was horrible (just look at net/mac80211/Makefile), and anyone adding a new algorithm would most likely not get it right at his first attempt. This patch therefore builds all enabled algorithms into the mac80211 module. The user interface for the rate control algorithms changes as follows: - first the user can choose which algorithms to enable (currently only MAC80211_RC_PID is available) - if more than one algorithm is enabled (currently not possible since only one algorithm is present) the user then chooses the default one Note: - MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=n Technical changes: - all selected algorithms get into the mac80211 module - net/mac80211/Makefile can now become much less complicated - support for rc80211_pid_algo.c being modular is no longer required - this includes unexporting mesh_plink_broken Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: John W.

* mac80211: move TX info into skb->cbJohannes Berg2008-05-211-5/+3
| | | | | | | | | | | | | | | | 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. To make it fit, a union is used where only data that is necessary for all steps is kept outside of the union. A number of fixes were done by Ivo, as well as the rt2x00 part of this patch.

* mac80211: use rate index in TX controlJohannes Berg2008-05-211-16/+9
| | | | | | | | | | | | | | | This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers. This mostly serves to reduce the TX control structure size to make it fit into skb->cb so that the fragmentation code can put it there and we can think about passing it to drivers that way in the future. The rt2x00 driver update was done by Ivo, thanks. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
