2008-06-14iwlwifi: map sw and hw ampdu queuesRon Rindjunsky
This patch maps sw and hw queues (for aggregations), so the right mac80211 queue will be waken when ieee80211_wake_queue is invoked.

2008-06-14iwlwifi: clean up in setup/cancel deferred workEmmanuel Grumbach
This patch makes some clean up in setup/cancel_deferred_work. iwl_setup_deferred_work does the work that is common to 4965 and 5000, then it calls to HW specific handlers. This patch also removes uneeded work_struct from iwl_priv.

This patch removes CONFIG_IWL4965_HT #ifdefs for iwl 4965 and 5000. 11n feature is stable in those drivers and its mode of operation is determined in mac80211, so this dependency is not needed any more.

2008-06-14rt2x00: Rework alignment check.Gertjan van Wingerde
Rework the alignment check in rt2x00dev.c to be independent of any potential alignment measures that may be taken before. Just check whether the payload is aligned based on the pointer addresses. Note: This is preparatory for the dynamically mapped skb buffers for the PCI drivers, as these need 4-byte alignment instead of the currently enforced offset by 2 bytes.

2008-06-14rt2x00: Fix double usage of skb->cb in USB RX path.Gertjan van Wingerde
It is not safe to use the skb->cb area for both the rxd and skb_frame_desc data at the same time, while they occupy an overlapping piece of memory. This can lead to hard to trace crashes as pointers within skb_frame_desc are pointing into nowhere, or the rxd data is overwritten with non-sense. Fix it by copying the rxd to a small buffer on the stack. Signed-off-by: Gertjan van Wingerde <gwingerde@kpnplanet.nl> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-06-14rt2x00: Centralize RX packet alignment handling in rt2x00lib.Gertjan van Wingerde
When rt2x00pci will be switched over to dynamically mapped skb's instead of statically allocated DMA buffers, it no longer can handle alignment of RX packets in a copy step, and needs to implement the same scheme as rt2x00usb does. In order to make the patch on dynamically mapped skb's smaller, already centralize the alignment handling into rt2x00lib. This allows us to move more code in rt2x00lib, and thus remove code duplication between rt2x00usb and rt2x00pci.

2008-06-14rt2x00: Don't kick TX queue after each frameIvo van Doorn
TX queues shouldn't be kicked after each frame that is put into the queue. This could cause problems during RTS and CTS-to-self as well as with fragmentation. In all those cases you want all frames to be send out in a single burst. Off course we shouldn't let the queue fill up entirely, thus we introduce a 10% threshold which, when reached, will force the frames to be send out regardless of the frame. In addition we should prevent queues to become full in such a way that the tx() handler can fail. Instead of stopping the queue when it is full, we should stop it when it is below the threshold.

2008-06-14rt2x00: Move generic TX frame writing code into rt2x00queueIvo van Doorn

2008-06-14rt2x00: Implement rt2x00usb_kick_tx_queue()Ivo van Doorn
rt2x00usb_kick_tx_queue() will loop over all entries within the INDEX_DONE->INDEX range and kick each entry which is pending to be kicked. This makes the kick_tx_queue approach work the same as with the PCI drivers which will allow for more code generalisation into rt2x00lib.

2008-06-14rt2x00: Fix queue initializationIvo van Doorn
qid should be initialized to QID_BEACON and QID_ATIM for the beacon and atim quue. This makes checking for a particular queue much saner, and it shouldn't harm, because the only places where the value is send to the hardware, we are allowed to send any value we want since it is only used as argument in the TX done register.

2008-06-14rt2x00: Make rt2x00_set/get_field macrosIvo van Doorn

2008-06-14rt2x00: Calculate register offset during compile timeIvo van Doorn
By using __ffs() the register offsets were always calculated at run-time which all FIELD32/FIELD16 definitions were builtin constants. This means we can heavily optimize the register handling by allowing GCC to do all the work during compilation. Add some compile_ffs() macros to perform the calculation at compile time. After this each rt2x00 module size is reduced by ~2500 bytes. And the stack size of several functions is reduced as well which further limits the number of rt2x00 results in 'make checkstack'. v2: Merge GertJan's bugfix of patch [1/11] directly into this patch       instead of providing it as seperate patch. v3: Add extra parentheses when bitshifting __x Signed-off-by: Gertjan van Wingerde <gwingerde@kpnplanet.nl> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-06-09libertas: fix sleep confirmationHolger Schurig
This fixes an issus that made "iwconfig eth1 power on" non-working. When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().

2008-06-09ipw2200: queue direct scansDan Williams
When another scan is in progress, a direct scan gets dropped on the floor. However, that direct scan is usually the scan that's really needed by userspace, and gets stomped on by all the broadcast scans the ipw2200 driver issues internally. Make sure the direct scan happens eventually, and as a bonus ensure that the passive scan worker is cleaned up when appropriate. The change of request_passive_scan form a struct work to struct delayed_work is only to make the set_wx_scan() code a bit simpler, it's still only used with a delay of 0 to match previous behavior.

Because ipw2200 and the ieee80211 stack don't actually cull old networks and place them back on the free list unless they are needed for new probe responses, over time the free list would become empty and creating an adhoc network would fail due to the ! list_empty(...) check.
