2021-04-21mt76: mt7921: abort uncompleted scan by wifi resetSean Wang1-0/+8
Scan abort should be required for the uncompleted hardware scan interrupted by wifi reset.

For MT7663, the availability of the patch files is used to detect, which corresponding firmware is going to be used (AP firmware or STA offload firmware).

2021-04-21rtlwifi: implement set_tim by update beacon contentPing-Ke Shih4-0/+37
Once beacon content is changed, we update the content to wifi card by send_beacon_frame(). Then, STA with PS can wake up properly to receive its packets. Since we update beacon content to PCI wifi devices every beacon interval, the only one usb device, 8192CU, needs to update beacon content when mac80211 calling set_tim. Reported-by: Maciej S.

2021-04-21rtw88: refine napi deinit flowPo-Hao Huang2-5/+15
We used to stop napi before disabling irqs. And it turns out to cause some problem when we try to stop device while interrupt arrives. To safely stop pci, we do three steps: 1. disable interrupt 2. synchronize_irq 3. stop_napi Since step 2 and 3 may not finish as expected when interrupt is enabled, use rtwpci->running to decide whether interrupt should be re-enabled at the time.

2021-04-21rtw88: Fix potential unrecoverable tx queue stopYu-Yen Ting1-2/+8
If there are lots of packets to be transmitted, the driver would check whether the available descriptors are sufficient according the read/write point of tx queue. Once the available descriptor is not enough, ieee80211_stop_queue is called. TX ISR, meanwhile, is releasing the tx resources after the packets are transmitted. This routine may call ieee80211_wake_queue by checking the available descriptor. The potential queue stop problem would occur when the tx queue is stopped due to the heavy traffic. Then thare is no chance to wake the queue up because the read point is not updated immediately, as a result, no more packets coulde be transmitted in this queue. This patch makes sure the ieee80211_wake_queue could be called properly and avoids the race condition when ring->r.rp, ring->queue_stopped are updated.
