2015-06-03iwlwifi: mvm: advertise only HW-supported ciphersJohannes Berg2-7/+27
After the new ciphers CCMP-256 and GCMP-128/256 were implemented, wpa_supplicant could start negotiating them and use the software implementation. This, however, breaks D3 behaviour in the driver since it means that WoWLAN will not be possible. To avoid breaking that feature, advertise only ciphers that the hardware supports.

2015-06-03iwlwifi: prepare for higher API/CAPA bitsJohannes Berg14-116/+161
Currently, loading the firmware fails when it has higher API or CAPA bits than the driver supports. That's an issue with integration. At the same time, actually using api[0] and capa[0] will become confusing when we also have api[1] and capa[1], and it's almost certain that we'll mix up the bits and use the bits for api[1] with api[0] by accident. Avoid all this by translating the API/CAPA bits to the regular kernel test_bit() format, and also providing wrapper functions. Also use the __bitwise__ facility of sparse to check that we're testing the right one.

2015-06-03iwlwifi: pcie: New RBD allocation modelSara Sharon3-97/+374
As a preperation for multiple RX queues change the RBD allocation model. The new model includes a background allocator. The allocator is called by the interrupt handler when there are two released buffers by the queue, and the allocator starts allocating eight pages per request. When the queue has released 8 pages it tries claiming the request. If the pages are not ready - it keeps claiming. This new model should make sure that RBDs are always available across the multiple queues. The RBDs are transferred between the allocator and the queue. The queue moves the free RBDs upon freeing them to the allocator. The allocator moves them back to the queue's possession when the request is claimed. The allocator has an initial pool to make sure there are always RBDs available for the request completion. Release of the buffers at exit is done per pools - the allocator frees its own initial pool and the queue frees its own pool. Existing code refactor - -Queue's initial pool is the size of the queue only as the allocation of the new buffers no longer uses this pool. -Removal of replenish background work, and replenish calls in the interrupt handler and restock(). -The replenish() and the rxq used_list are used only during initialization. -Moved page allocation to a new function for code reuse. New code - Allocator code - new structure and functions. Interrupt handler uses the allocator functions for replenishing buffers. Reuse of the restock() method.

2015-05-28iwlwifi: mvm: implement the BlockAck related debug triggersEmmanuel Grumbach5-10/+200
BlockAck sessions can have events that are interesting to debug. When we send or receive a BAR, it is may indicate that something bad is happening. Even more so when mac80211 tells us that a frame timed out in the reodering buffer. Add a few triggers for BlockAck session debugging. Allow per-TID debugging.

2015-05-28Merge tag 'mac80211-next-for-davem-2015-05-06' into iwlwifi-nextEmmanuel Grumbach44-175/+99
Lots of updates for net-next for this cycle. As usual, we have a lot of small fixes and cleanups, the bigger items are: * proper mac80211 rate control locking, to fix some random crashes (this required changing other locking as well) * mac80211 "fast-xmit", a mechanism to reduce, in most cases, the amount of code we execute while going from ndo_start_xmit() to the driver * this also clears the way for properly supporting S/G and checksum and segmentation offloads
2015-05-28iwlwifi: mvm: treat scan races also on UMAC scansLuciano Coelho1-10/+2
For UMAC, we were not treating a race condition that happens in the scan flows, because it was not using the same state flags. Now that UMAC and LMAC scans use the same state flags, we can also handle the race conditions for UMAC.

2015-05-28iwlwifi: mvm: make UMAC scans use the stopping scan statusLuciano Coelho1-17/+15
UMAC scans now use the general scan status for almost everything, the only part missing was in the scan complete notifications. Change it to use the stopping flags instead of clearing the flags when the stop comes from above and clean the handler function a bit.
