2016-07-06iwlwifi: pcie: enable interrupts before releasing the NIC's CPUEmmanuel Grumbach1-1/+4
The NIC's CPU gets started after the firmware has been written to its memory. The first thing it does is to send an interrupt to let the driver know that it is running. In order to get that interrupt, the driver needs to make sure it is not masked. Of course, the interrupt needs to be enabled in the driver before the CPU starts to run. I mistakenly inversed those two steps leading to races which prevented the driver from getting the alive interrupt from the firmware. Fix that.

2016-07-06iwlwifi: mvm: add support for GCMP encryptionAyala Beker6-24/+85
Newer hardware supports GCMP and GCMP 256-bit ciphers. Add support for adding/setting GCMP key for TX mode. In the TX command handling GCMP-256 is handled in a different way as the key size should be up to 128-bits: Set the key value to the key index in the key table, and specify that this key should be taken form the key table instead of from the TX command.

2016-07-06iwlwifi: mvm: fix txq aggregation bugOren Givon1-1/+9
Fix an issue where nullfunc frames and block ack requests had the same tid as aggregation frames and were queued on a non aggregation queue. The pending frames counter included those frames but the check whether to decrement the pending frames counter relied on the tid status and not on the txq id. The result was an inconsistent state of the pending frames counter followed by a failure to remove the station. This failure triggered SYSASSERT 0x3421. In addition, fix a situation in DQA mode where the number of pending frames turned negative. This was due to the TX queue being on the IWL_EMPTYING_HW_QUEUE_DELBA state and its frames were still decremented. Even though the SYSASSERT issue is fixed when DQA is disabled, the issue is not completely solved when DQA is enabled and should still be fixed.

2016-07-06iwlwifi: mvm: avoid harmless -Wmaybe-uninialized warningArnd Bergmann1-20/+21
gcc is apparently unablel to track the state of the local 'resp_v2' variable across the kzalloc() function, and warns about the response variable being used without an initialization: drivers/net/wireless/intel/iwlwifi/mvm/nvm.c: In function ‘iwl_mvm_update_mcc’: drivers/net/wireless/intel/iwlwifi/mvm/nvm.c:727:36: warning: ‘mcc_resp_v1’ may be used uninitialized in this function [-Wmaybe-uninitialized] resp_cp->n_channels = mcc_resp_v1->n_channels; drivers/net/wireless/intel/iwlwifi/mvm/nvm.c:721:3: warning: ‘mcc_resp’ may be used uninitialized in this function [-Wmaybe-uninitialized] memcpy(resp_cp, mcc_resp, resp_len); The warning showed up in x86 allmodconfig after my patch to unhide -Wmaybe-uninitialized warnings by default was merged, though it always existed in randconfig builds. I did not catch the warning earlier because I was testing on ARM, which never produced the warning. This rearranges the code in a way that improves readability for both humans and the compiler, and that avoids the warning.

Set the correct sta_id in the SCD_QUEUE_CONFIG command sent to the FW when enabling/disabling queues. This is needed in DQA-mode to allow the FW to associate between queue and STA. In case the queue isn't connected to a specific station but rather is a static "generic" queue - the sta_id should be set to 0x10 (max supported STA is 0x0f).

2016-07-06iwlwifi: mvm: support dqa queue sharingLiad Kaufman7-22/+199
Support DQA queue sharing when no free queue exists for allocation to a STA that already exists. This means that a single queue will serve more than a single TID (although the RA will be the same for all TIDs served). We try to choose the lowest AC possible, to ensure the shared queues have the lowest possible combined AC requirements. The queue to share is chosen only from the same RA's DATA queues as follows (in descending priority): 1. An AC_BE queue 2. Same AC queue 3. Highest AC queue that is lower than new AC 4. Any existing AC (there always is at least 1 DATA queue) If any aggregations existed for any of the TIDs of the shared queue - they are stopped (the FW is notified), but no delBA is sent.

2016-07-06iwlwifi: mvm: fix possible division by zeroSara Sharon1-0/+3
Theoretically we may get only one IRQ from OS, in which case we will have only 1 queue even in MSIx mode. This will cause division by zero in the indirection table calculation. We do not need send the command in that case, as there is only one queue so all RX traffic will be directed to it anyway. Bail out early if there is only one queue.

Support marking queues as inactive upon a timeout expiring, and allow inactive queues to be re-assigned to other RA/TIDs if no other queue is free. This is done by keeping a timestamp of the latest frame TXed for every RA/TID, and then going over the queues currently in use when a new queue is needed, inactivating all those that are inactive.

2016-07-01iwlwifi: pcie: workaround HW shadow registers bugSara Sharon6-9/+35
Integrated 9000 devices have a bug with shadow registers value retention. If driver writes RBD registers while MAC is asleep the values are stored in shadow registers to be copied whenever MAC wakes up. However, in 9000 devices a MAC wakeup is not triggered and when the bus powers down due to inactivity the shadow values and dirty bits are lost. Turn on the chicken-bits that cause MAC wakeup for RX-related values as well when the device is in D0. When the device is in low power mode turn the RX wakeup chicken bits off since driver is idle and this W/A is not needed. Remove previous W/A which was ineffective.

2016-07-01iwlwifi: mvm: do not trust NSSN for amsdu sub-framesSara Sharon1-2/+18
We cannot trust NSSN for AMSDU sub-frames that are not the last. The reason is that NSSN advances on the first sub-frame, and may cause the reorder buffer to advance before all the sub-frames arrive. Example: Reorder buffer contains SN 0 & 2. We receive AMSDU with SN 1 and NSSN for first sub frame 3. The result us that driver releases SN 0,1, 2. When sub-frame 1 arrives - reorder buffer is already ahead and it will be dropped. If the last sub-frame is not on this queue - we will get frame release notification with up to date NSSN.

The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K.
