2008-08-29b43: Rewrite TX power adjustmentmaster-2008-08-29Michael 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
This patch implements a dynamic "ops" based PHY API. This is needed in order to conveniently support future PHY types to avoid the "switch"-hell. This patch does not change any functionality. It just moves lots of code from one place to another and adjusts it for the changed data structures. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

2008-08-29rt2x00: skb->data pointer should not include TX descriptorMattias Nissler
Make sure the skb->data pointer points to the frame data, not the TX descriptor. The frame dumping code relies on that. Signed-off-by: Mattias Nissler <mattias.nissler@gmx.de> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-08-29rt2x00: Add Signal type flagIvo van Doorn
Instead of using the PLCP flag to indicate if the signal value is plcp or the bitrate we should add a new flag to mark the bitrate type explicitely. This is usefull when new types are added later for rt2800. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-08-29rt2x00: Initialize txop during conf_tx() callbackIvo van Doorn
The txop parameter is supported by rt61pci and rt73usb, and thus should be written to the register instead of using the fixed value set during initialization. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-08-29rt2x00: Only configure hardware when radio is enabledMattias Nissler
Some hardware configuration registers such as antenna and channel configuration can only be written when the radio is enabled. Previously, we didn't consider this, so some configuration items could be set inconsistently after reenabling the radio. This patch changes the config() handler to only reprogram the hardware when the radio is enabled. Configuration changes that are made while the radio is off are postponed until the radio is switched back on. We also leave the radio turned off during initialization and only enable it when requested by mac80211. This allows us to get rid of the DIRTY_CONFIG flag, because the device is now guaranteed to be completely initialized when brought up by mac80211.

2008-08-29rt2x00: Map extra_tx_headroom to DMAIvo van Doorn
If a driver requests additional headroom it should be mapped to DMA as well because it will be send to the hardware as well (as form of extra descriptor). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-08-29rt2x00: Fix race conditions in flag handlingIvo van Doorn
Some of the flags should be accessed atomically to prevent race conditions. The flags that are most important are those that can change often and indicate the actual state of the device, queue or queue entry. The big flag rename was done to move all state flags to the same naming type as the other rt2x00dev flags and made sure all places where the flags were used were changed. ;) Thanks to Stephen for most of the queue flags updates, which fixes some of the most obvious consequences of the race conditions. Among those the notorious: rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.

2008-08-29p54: fix rssi auto calibrationChristian Lamparter
Ever wondered why the signal was so bad with p54 compared to madwifi, or intel? Well, if you have revision 1 rssi calibration curve points in your EEPROM, then wonder no more. The firmware wants a extra 1 byte padding for every curve point. But someone forgot to put them into the EEPROM's data structure... So now, big question: what happens when we blindly "memcpy" these data points? Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-08-29ssb: Clean up extraction of MAC addresses from SPROMLarry Finger
Only rev 1 and 2 ssb SPROMs have fields named et0mac and et1mac; however, all of the extraction routines extract pseudo data for these fields from regions that are all 1's resulting in a hardware address of FF:FF:FF:FF:FF:FF. This patch forces such a fill at the beginning of the data extraction process, and only does the formal extraction if the SPROM rev is 1 or 2.

2008-08-29mac80211: Handle scan result IEs in one blockJouni Malinen
Clean up and extend scan result processing by storing all the IEs from Beacon/Probe Response frames in a single block instead of allocating memory for each specific IE separately.

In addition, the remaining ath_skb_{map,unmap}_single() wrapper calls are replaced with direct pci_{map,unmap}_single() calls in beacon.c.
