2009-04-28iwlwifi: notify on scan completion even when shutting downJohannes Berg
Under certain circumstances iwlwifi can get stuck and will no longer accept scan requests, because the core code (cfg80211) thinks that it's still processing one. This fixes one of the points where it can happen, but I've still seen it (although only with my radio-off-when-idle patch).

2009-04-28wireless: remove unneeded EXPORT_SYMBOL the tickles a powerpc compiler bugStephen Rothwell
drivers/net/wireless/iwlwifi/iwl3945-base.c:1415: error: __ksymtab_iwl3945_rx_queue_reset causes a section type conflict I am pretty sure that this is a compiler bug, so not to worry. However, as far as I can see, iwl-3945.o (the only user) and iwl3945-base.o are always linked into the same module, so the EXPORT_SYMBOL (which causes the problem) should not be needed. Correct?

2009-04-21iwlwifi: DMA fixesReinette Chatre
A few issues wrt DMA were uncovered when using the driver with swiotlb. - driver should not use memory after it has been mapped - iwl3945's RX queue management cannot use all of iwlagn because the size of the RX buffer is different. Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that.

2009-04-21iwlwifi: add debugging for TX pathReinette Chatre
When debugging TX issues it is helpful to know the seq nr of the frame being transmitted. The seq nr is printed as part of ucode's log informing us which frame is being processed. Having this information printed in driver log makes it easy to match activities between driver and firmware. Also make possible to print TX flags directly. These are already printed as part of entire TX command, but having it printed directly in cpu format makes it easier to look at.

2009-03-27mac80211/iwlwifi: move virtual A-MDPU queue bookkeeping to iwlwifiJohannes Berg
This patch removes all the virtual A-MPDU-queue bookkeeping from mac80211. Curiously, iwlwifi already does its own bookkeeping, so it doesn't require much changes except where it needs to handle starting and stopping the queues in mac80211. To handle the queue stop/wake properly, we rewrite the software queue number for aggregation frames and internally to iwlwifi keep track of the queues that map into the same AC queue, and only talk to mac80211 about the AC queue. The implementation requires calling two new functions, iwl_stop_queue and iwl_wake_queue instead of the mac80211 counterparts.
