2008-09-05cfg80211: keep track of supported interface modesLuis R. Rodriguez
It is obviously good for userspace to know up front which interface modes a given piece of hardware might support (even if adding such an interface might fail later because of concurrency issues), so let's make cfg80211 aware of that. For good measure, disallow adding interfaces in all other modes so drivers don't forget to announce support for one mode when they add it.

2008-08-29b43: Rewrite TX power adjustmentMichael Buesch
This patch rewrites the TX power recalculation algorithms to scale better with changed enviromnent. If there's low TX traffic, the power will be checked against the desired values every 60 seconds. If there is high TX traffic, the check is redone every 2 seconds. This improves the reaction times a lot and confuses the rate control less. It will also reduce the time it initially takes to tune to a new TX power value. With the old algorithm it could take about 30 to 45 seconds to settle to a new power value. This will happen in about two to four seconds now. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-08-29b43: Implement dynamic PHY APIMichael Buesch

2008-07-15wireless: fix warnings from QoS patchJohannes Berg

2008-07-14mac80211: revamp beacon configurationJohannes Berg
This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

2008-05-21mac80211: move TX info into skb->cbJohannes Berg
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.

2008-05-21mac80211: use rate index in TX controlJohannes Berg
This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers.

2008-05-14mac80211: use hardware flags for signal/noise unitsBruno Randolf
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

2008-05-07b43: Rewrite LO calibration algorithmMichael Buesch
This patch distributes the Local Oscillator calibration bursts over time, so that calibration only happens when it's actually needed. Currently we periodically perform a recalibration of the whole table. The table is huge and this takes lots of time. Additionally only small bits of the table are actually needed at a given time. So instead of maintaining a huge table with all possible calibration values, we create dynamic calibration settings that a) We only calibrate when they are actually needed. b) Are cached for some time until they expire. So a recalibration might happen if we need a calibration setting that's not cached, or if the active calibration setting expires. Currently the expire timeout is set to 30 seconds. We may raise that in future. This patch reduces overall memory consumption by nuking the huge static calibration tables. This patch has been tested on several 4306, 4311 and 4318 flavours.
