2013-10-02iwlwifi: pcie: don't reset the TX queue counterEmmanuel Grumbach1-0/+2
A few NICs can get into trouble if we reset the TX queue counters in certain very rare situation. To be on the safe side, simply avoid to reset the TX queue counter. This is relevant for non-AMPDU queues only since on AMPDU we have no choice - we must start the TX queue at the right index.

2013-09-25iwlwifi: Remove extern from function prototypesJoe Perches4-11/+10
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

2013-08-16iwlwifi: mvm: Add PBW snoozing enablementAlexander Bondar5-2/+54
The Performance Based Window snooze mechanism is based on uAPSD and is used in low-medium traffic scenarios, in order to provide better power performance while insuring low latency and jitter for the incoming traffic. This patch enables PBW snoozing in case uAPSD is enabled and all ACs are uAPSD trigger and delivery enabled.

Use beacon statistics notification to track RSSI. Notify mac80211 when the tresholds are crossed. The roaming treshold is configured to be equal to cqm_thold. If the beacon filtering command is not supported by fw fall back and use mac80211 mechanism.

2013-08-16iwlwifi: return -ENOMEM instead of NULL when OOM in iwl_drv_start()Luciano Coelho2-4/+6
The callers of iwl_drv_start() are probe functions. If a probe function returns 0, it means it succeeded. So if NULL was returned by iwl_drv_start(), it would be considered as a success. Fix this by returning -ENOMEM if the driver struct allocation fails in iwl_drv_start(). Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-08-16iwlwifi: mvm: refactor resume from WoWLAN codeJohannes Berg1-63/+88
To be able to add more logic to the resume code, refactor it a bit, moving some status checking/reporting logic into a new function. The locking becomes a bit odd (one of the new functions now unlocks the mutex) but this will be required to call new mac80211 APIs in there later.

2013-08-12iwlwifi: pcie: don't swallow error codes in iwl_trans_pcie_alloc()Luciano Coelho2-13/+17
The iwl_trans_pcie_alloc() function doesn't pass up error codes returned from functions it calls, swallowing them and returning NULL in all failure cases. The caller checks if the return value is NULL and returns -ENOMEM. This is not correct, because in certain cases the failure was not due to an OOM situation. To fix this, modify the iwl_trans_pcie_alloc() function to use ERR_PTR() to return error codes and clean up the error handling code a bit.
