2009-02-27mac80211: Introduce a generic commit() to apply changesAlina Friedrichsen
This patch introduces a generic commit() function which initiate a new network joining process. It should be called after some interface config changes, so that the changes get applied more cleanly. Currently set_ssid() and set_bssid() call it. Others can be added in future patches. In version 1 the header files was forgotten, sorry.

2009-02-27ath9k: Don't reset TSF after scanning automaticallyAlina Friedrichsen
Reset automatically the TSF on re-enabling beaconing after scanning in IBSS mode causes several problems. For example a new created IBSS network can't age before an other node has joined, because scans are done automatically in that case. And several other strange bugs more... The TSF reset is done manually in the higher level mac80211 code in the cases were it's needed, so we don't need to do it here.

2009-02-27b43: Optimize DMA buffersMichael Buesch
In the old days we used one slot per frame. But when we changed that to 2, we didn't raise the overall slot count. Which resulted in an effective division of two to the number of slots. Double the number of TX slots, so we have an effective hardware queue of 128 frames per QoS queue. Also optimize the TX header cache handling. We don't need a cached TX header for slots that will never carry an actual header. So we reduce the memory consumption of the cache by 50%. So as a net result we end up with more or less the same memory usage before and after this patch (except a few tiny meta structures), but have twice the number of TX slots available.

2009-02-27b43: Fix DMA buffer size handlingMichael Buesch
This fixes hidden bugs in the size handling of the DMA buffers. This sets the RX buffer size to the theoretical max packet size and fixes passing of the size values to the device (must not subtract the header offset). These bugs are hidden and don't actually trigger due to the magic +100 offset for the buffer size. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-02-27iwlwifi: dma mapping read and write changesFenghua Yu
When iwlwifi runs on IOMMU, IOMMU generates a lot of PTE write faults because PTE write bit is not set on some of PTE's. This is because iwlwifi driver calls DMA mapping with PCI_DMA_TODEVICE which is read only in mapping PTE. But iwlwifi device actually writes to the mapped page to update its contents. This issue is not exposed in swiotlb. But VT-d hardware can capture this fault and stop the fault transaction. The iwl TX command contains a scratch field that is updated by uCode to indicate retry counts. For 5000 series the patch is required also for regular frames, but this patch does not differenciate.

Default to MAX_UCODE_BEACON_INTERVAL if the output of iwl_adjust_beacon_interval would otherwise be zero. This prevents a division by zero on my iwl5300-equipped Lenovo T400 with kernels that include "mac80211: use cfg80211s BSS infrastructure". This patch is a bit of a hack -- I'm not sure why iwl_setup_rxon_timing is giving iwl_adjust_beacon_interval a zero input (which is the only way it would output zero). I would be happy to have a better fix. But for now, this makes my box boot... Signed-off-by: John W. Linville <linville@tuxdriver.com>

So fill qual.qual with the qual.level value clamped to -110..-40 dBm or just the regular 'unspecified' signal level.
