2008-03-07iwlwifi: use mac80211_tx_control_flagsRon Rindjunsky
This patch makes use of the new mac80211_tx_control_flags and tx_rate to pass Tx data, regular and 11n, from the HW tx response into the rate scaling.

2008-03-07mac80211: adding mac80211_tx_control_flags and HT flagsRon Rindjunsky
This patch makes enum from the defines previously dwelled inside ieee80211_tx_control for better readability. The patch also addes HT flags, for 802.11n drivers: - IEEE80211_TXCTL_OFDM_HT: request low-level driver to use HT OFDM rates - IEEE80211_TXCTL_GREEN_FIELD: use green field protection - IEEE80211_TXCTL_DUP_DATA: duplicate data on both 20 Mhz channels - IEEE80211_TXCTL_40_MHZ_WIDTH: send this frame in 40Mhz width - IEEE80211_TXCTL_SHORT_GI: send this frame with short guard interval Tx command can be a combination of any of these flags, along with bitrate represented by ieee80211_rate. this will allow legacy drivers to switch easily to any 11n rate representation.

2008-03-07b43: Add TX statistics debugging countersMichael Buesch
This adds a few debugging counters, that are useful for debugging the "card does not transmit" or "connection is unstable" kind of problems. It's also useful for tuning an RC algorithm. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-03-07b43: Rename the DMA ring pointersMichael Buesch
Rename the DMA ring pointers to have more descriptive and standard names. Also remove the 6th unused TX ring. We can add it back later, if we need it. The unused TX-status rx-ring is also removed, as that's only used by legacy devices not supported by this driver anyway. This is no functional change, except less memory allocation for the removed rings. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Make some changes which mimic what we see in register dumps. This patch does not add a helper to ath5k_hw_reset(). It does seem clear we need a re-shuffle around ath5k_hw_reset() though as code in there is lengthy and already hitting 80-char limit. This can be dealt with later though.

2008-03-07ath5k: Remove RF5413 from rf gain optimization functionsNick Kossifidis
* Since RF2413 it seems that RF_BUFFER settings are different (notice that the last part -"bank 7" or whatever- is smaller than in 5111/5112).

2008-03-06zd1211rw: support for mesh interface and beaconingLuis Carlos Cobo
The previously unused CR_CAM_MODE register is set to MODE_AP_WDS. This makes the driver ack mesh (WDS) frames. It does not affect Infra functionality of the driver. Previously missing beaconing support has been added. This might also help implement a currently missing ah-hoc mode. Support for interrupts from the device have been added, but we are not handling most of them. Mesh interfaces are considered associated as long as the interface is up.

2008-03-06mac80211: always insert key into listJohannes Berg
Today I hit one of my new WARN_ONs in the mac80211 code because a key wasn't being freed correctly. After wondering for a while I finally tracked it to the fact that STA keys aren't added to the per-sdata key list correctly, they are supposed to always be on that list, not just for default keys.

2008-03-06b43: verify sta_notify mac80211 callbackJohannes Berg

2008-03-06mac80211: fix sta_info mesh timer bugJohannes Berg
I noticed a bug I introduced when mesh is enabled: sta_info_destroy() will end up calling cancel_timer() on a timer that has never been initialized because the timer is only initialized in mesh_plink_alloc(), not in sta_info_alloc(). This patch moves the initialization of all mesh related fields into sta_info_alloc(), adds a bit of sanity checking to the cfg80211 handlers and sta_info_insert() and makes mesh_plink_alloc() a static helper function that is only used from the mesh plink code.

2008-03-06mac80211: add documentation bookJohannes Berg
Quite a while ago I started this book. The required kernel-doc patches have since gone into the tree so it is now possible to build the book in mainline. The actual documentation is still rather incomplete and not all things are linked into the book, but this enables us to edit the documentation collaboratively, hopefully driver authors can add documentation based on their experience with mac80211.

2008-03-06mac80211: remove STA entries when taking down interfaceJohannes Berg
When we take down an interface, we need to remove the STA info items that belong to it because otherwise we might invoke a sta_notify() callback in the driver when we later delete the STA entries, but in that case the driver will already have removed its knowledge of the interface they belonged to leading to confusion. Also, we could invoke the set_tim() callback after the driver removed its knowledge of the interface, which can lead to a crash if it requests a beacon with a then-invalid vif pointer! A side effect of this patch is that, because it was easier, it disallows changing the WDS peer while an interface is up. Should that actually be necessary, it can be added back, but the WDS peer STA entry may not be added while the interface is UP so for now I've simplified the WDS peer's STA entry lifetime management.

2008-03-06mac80211: clean up sta_info and document lockingJohannes Berg
This patch cleans up the sta_info struct and documents how each set of variables is locked. Notably, flags locking is completely missing.

2008-03-06mac80211: split sta_info_addJohannes Berg
sta_info_add() has two functions: allocating a station info structure and inserting it into the hash table/list. Splitting these two functions allows allocating with GFP_KERNEL in many places instead of GFP_ATOMIC which is now required by the RCU protection. Additionally, in many places RCU protection is now no longer needed at all because between sta_info_alloc() and sta_info_insert() the caller owns the structure. This fixes a few race conditions with setting initial flags and similar, but not all (see comments in ieee80211_sta.c and cfg.c). More documentation on the existing races will be in a follow-up patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
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.
