2016-08-30iwlwifi: mvm: support txq tid owner changeLiad Kaufman
Every active TXQ is assigned to a TID given through the SCD_CONFIG_CMD, and acts as an identifier in the FW. However, there may be cases this ownership needs to be changed. For example, in the following scenario: 1. TID x is owner of a queue 2. Due to a shortage of queues, TID y and z share with x 3. TID x becomes inactive and needs to be removed from the shared queue. In this scenario, if another queue is freed and traffic on x continues, we can't allocate it a new queue as long as it is the owner of the first queue. Support moving ownership of a TXQ to a different TID (same STA) without stopping the queue. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-08-30iwlwifi: mvm: use defines for SCD_CONFIG_CMD enablementLiad Kaufman
Due to the addition of another option in the SCD_CONFIG_CMD's %enable field, change the assignment of this field to use defines rather than hard-code the value itself. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-08-30iwlwifi: mvm: re-assign old queues after hw restart in dqa modeLiad Kaufman
When working in DQA mode, if a queue is shared and a HW restart occurs, there might be a possible race condition between stations on the queues, and an existing queue might be left with no queues. To solve this, make sure in DQA mode to re-assign the same queues as before the HW restart. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-08-30iwlwifi: mvm: keep track of tid associated with each queueLiad Kaufman
When sending the SCD_QUEUE_CONFIG command, the queue is associated to a specific TID. If later there is a need to use this TID on a different queue instead, it first needs to be unassociated from the first queue. Keep track for every queue what TID is associated with it.

2016-08-30iwlwifi: mvm: re-aggregate shared queue after unsharingLiad Kaufman
When a shared queue becomes unshared, aggregations should be re-enabled if they've existed before. Make sure that they do this, if required. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2016-08-29iwlwifi: mvm: support GMAC protocolAyala Beker
Add support for installing and removing GMAC key for newer FW versions that support GCM and MFP. GMAC provides authentication and integrity for multicast management frames.

2016-08-29iwlwifi: mvm: allow same PN for de-aggregated AMSDUSara Sharon
The 9000 hardware will de-aggregate AMSDUs. In the process it will copy the mac header "as is" to the new MPDUs. This means driver should allow the same PN for MPDUs originated from the same AMSDU. Do that by incrementing the PN only for the last MPDU in the sequence. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2016-08-24brcmfmac: Change vif_event_lock to spinlockmhiramat@kernel.org
Change vif_event_lock to spinlock from mutex, since this lock is used in wait_event_timeout() via vif_event_equals(). This caused a warning report as below. As far as I can see, this lock protects regions where updating structure members, not function calls. Also, since those regions are not called from interrupt handlers (of course, it was a mutex), spin_lock is used instead of spin_lock_irqsave.

2016-08-24brcmfmac: Check rtnl_lock is locked when removing interfacemhiramat@kernel.org
Check rtnl_lock is locked in brcmf_p2p_ifp_removed() by passing rtnl_locked flag. Actually the caller brcmf_del_if() checks whether the rtnl_lock is locked, but doesn't pass it to brcmf_p2p_ifp_removed(). Without this fix, wpa_supplicant goes softlockup with rtnl_lock holding (this means all other process using netlink are locked up too) e.g. [ 4495.876627] INFO: task wpa_supplicant:7307 blocked for more than 10 seconds.

2016-08-19wil6210: fix wiphy registration sequenceLior David
Currently wiphy structure is initialized and registered in wil_if_alloc, before some information is available such as MAC address and capabilities. As a result there is a small chance user space will get incorrect information from calls such as NL80211_CMD_GET_WIPHY.

2016-08-04tree-wide: replace config_enabled() with IS_ENABLED()Masahiro Yamada
The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.
