2016-10-07iwlmvm: mvm: set correct state in smart-fifo configurationstriebit
commit 849a9627299100ae3f0ce573fc87d2b476f3bb59 upstream. Currently the state sent in SF configuration is always FULL_ON.

2016-05-04iwlwifi: mvm: fix memory leak in pagingMatti Gottlieb
commit 7fdf9663261cc77a516396fec82cee8a8ea07e76 upstream. Currently paging download buffer is freed during the the unloading of the opmode which happens when the driver is unloaded. This causes a memory leak since the paging download buffer is allocated every time we enable the interface, so the download buffer can be allocated many times, but only be freed once. Free paging download buffer during disabling of the interface.

2016-03-16iwlwifi: mvm: inc pending frames counter also when txing non-staLiad Kaufman
commit fb896c44f88a75843a072cd6961b1615732f7811 upstream. Until this patch, when TXing non-sta the pending_frames counter wasn't increased, but it WAS decreased in iwl_mvm_rx_tx_cmd_single(), what makes it negative in certain conditions. This in turn caused much trouble when we need to remove the station since we won't be waiting forever until pending_frames gets 0. In certain cases, we were exhausting the station table even in BSS mode, because we had a lot of stale stations. Increase the counter also in iwl_mvm_tx_skb_non_sta() after a successful TX to avoid this outcome.

2016-03-03iwlwifi: mvm: don't allow sched scans without matches to be startedLuca Coelho
commit 5e56276e7555b34550d51459a801ff75eca8b907 upstream. The firmware can perform a scheduled scan with not matchsets passed, but it can't send notification that results were found. Since the userspace then cannot know when we got new results and the firmware wouldn't trigger a wake in case we are sleeping, it's better not to allow scans without matchsets.

2015-11-15iwlwifi: mvm: don't overwrite the key indices in D3 entryLuca Coelho
When entering D3, we need to use hardcoded key indices because the firmware requires that. To do so, we are overwriting the HW key index in the keyconf structure, which makes it impossible to reuse the indices that were used before entering D3. Additionally, we overwrite all the non-PTK keys with index 1, because the firmware only allows one non-PTK key to be set. This is bad, because when we resume, we may try to set more than one key with index 1, which will obviously fail. To fix this, allow the callers to set a pre-defined index to use in iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from the keyconf struct (which requires overwriting it). In normal cases, the caller can pass STA_KEY_IDX_INVALID, which will cause a new key offset to be chosen. During HW_RESTART, we pass the offset that is in use. And during D3 entry, we pass the hardcoded indices we need to use. Additionally, don't clear the fw_key_table in D3 entry, so that the flags are still set with the pre-D3 values when exiting D3. fixes=I3165c22362483f0152d9ec1d2a987fb5529727c1 Fixes: b546dcd6b742 ("iwlwifi: mvm: don't reset key index on HW restart") Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2015-10-13cfg80211: Add multiple scan plans for scheduled scanAvraham Stern
Add the option to configure multiple 'scan plans' for scheduled scan. Each 'scan plan' defines the number of scan cycles and the interval between scans. The scan plans are executed in the order they were configured. The last scan plan will always run infinitely and thus defines only the interval between scans. The maximum number of scan plans supported by the device and the maximum number of iterations in a single scan plan are advertised to userspace so it can configure the scan plans appropriately. When scheduled scan results are received there is no way to know which scan plan is being currently executed, so there is no way to know when the next scan iteration will start. This is not a problem, however. The scan start timestamp is only used for flushing old scan results, and there is no difference between flushing all results received until the end of the previous iteration or the start of the current one, since no results will be received in between.

In some scenarios where the success ratio isn't >85% such a rate could be too aggressive leading us to avoid the new column. This has the potential of causing sub optimal performance.

"DQA" is shorthand for "dynamic queue allocation", with the idea of allocating queues per-RA/TID on-demand rather than using shared queues statically allocated per vif. The goal of this is to enable future features (like GO PM) and to improve performance measurements of TX traffic. When RA/TID streams can't be neatly sorted into different AC queues, DQA allows sharing queues for the same RA. This means that DQA allows different ACs may reach the same HW queue.
