This field was added to wl_sta struct to get hw in situations where it was not given to driver by mac80211. In our case, get_expected_throughput op did not send hw to driver. This patch reverts the change, as it is no longer needed due to commit 4fdbc67a25ce ("mac80211: call get_expected_throughput only after adding station") as hw is now sent as a parameter.

Commit 97f2645f358b ("tree-wide: replace config_enabled() with IS_ENABLED()") mostly did away with config_enabled(). This is one of the postponed TODO items as config_enabled() is used for a tristate option here. Theoretically, config_enabled() is equivalent to IS_BUILTIN(), but I guess IS_REACHABLE() is the best fit for this case because both CONFIG_HWMON and CONFIG_ATH10K are tristate.

2016-09-02ath10k: fix sending frame in management path in push txq logicAshok Raj Nagarajan1-0/+20
In the wake tx queue path, we are not checking if the frame to be sent takes management path or not. For eg. QOS null func frame coming here will take the management path. Since we are not incrementing the descriptor counter (num_pending_mgmt_tx) w.r.t tx management, on tx completion it is possible to see negative values. When the above counter reaches a negative value, we will not be sending a probe response out. if (is_presp && ar->hw_params.max_probe_resp_desc_thres < htt->num_pending_mgmt_tx) For IPQ4019, max_probe_resp_desc_thres (u32) is 24 is compared against num_pending_mgmt_tx (int) and the above condtions comes true if the counter is negative and we drop the probe response. To avoid this, check on the wake tx queue path as well for the tx path of the frame and increment the appropriate counters Fixes: cac085524cf1 "ath10k: move mgmt descriptor limit handle under mgmt_tx" Signed-off-by: Ashok Raj Nagarajan <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2016-09-02ath10k: improve wake_tx_queue ops performanceRajkumar Manoharan1-1/+17
txqs_lock is interfering with wake_tx_queue submitting more frames. so queues don't get filled in and don't keep firmware/hardware busy enough. This change helps to reduce the txqs_lock contention and wake_tx_queue() blockage to being possible in txrx_unref(). To reduce turn around time of wake_tx_queue ops and to maintain fairness among all txqs, the callback is updated to push first txq alone from pending list for every wake_tx_queue call. Remaining txqs will be processed later upon tx completion. Below improvements are observed in push-only mode and validated on IPQ4019 platform. With this change, in AP mode ~10Mbps increase is observed in downlink (AP -> STA) traffic and approx. 5-10% of CPU usage is reduced. Major improvement is observed in 1-hop Mesh mode topology in 11ACVHT80. Compared to Infra mode, CPU overhead is higher in Mesh mode due to path lookup and no fast-xmit support. So reducing spin lock contention is helping in Mesh.
