wifi: mac80211: add support to call csa_finish on a link

2024-02-08T14:00:45Z

Currently ieee80211_csa_finish() function finalizes CSA by scheduling a finalizing worker using the deflink. With MLO, there is a need to do it on a given link basis. Pass link ID of the link on which CSA needs to be finalized. Signed-off-by: Aditya Kumar Singh Link: https://msgid.link/20240130140918.1172387-6-quic_adisi@quicinc.com Signed-off-by: Johannes Berg

wifi: fill in MODULE_DESCRIPTION()s for mt76 drivers

wifi: mt76: mt7921s: fix workqueue problem causes STA association fail

2023-12-07T17:50:22Z

The ieee80211_queue_work function queues work into the mac80211 local->workqueue, which is widely used for mac80211 internal work processes. In the mt76 driver, both the mt76-sido-status and mt76-sdio-net threads enqueue workers to the workqueue with this function. However, in some cases, when two workers are enqueued to the workqueue almost simultaneously, the second worker may not be scheduled immediately and may get stuck for a while. This can cause timing issues. To avoid these timing conflicts caused by worker scheduling, replace the worker with an independent thread.

wifi: mt76: Convert to platform remove callback returning void

2023-12-07T17:50:22Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert the three mt76 drivers from always returning zero in the remove callback to the void returning variant.

wifi: mt76: introduce wed pointer in mt76_queue

2023-12-07T17:50:20Z

Introduce mtk_wed_device pointer in mt76_queue structure in order to configure WED chip. Get rid of dev parameter in Q_READ and Q_WRITE macros. Introduce wed parameter to the following routine signatures: - mt76_init_queue - mt76_init_tx_queue This is a preliminary patch to introduce WED support for mt7996 since mt7996 runs two separate WED chips.
