2022-02-23mt76: mt7915: fix injected MPDU transmission to not use HW A-MSDUJohan Almbladh
Before, the hardware would be allowed to transmit injected 802.11 MPDUs as A-MSDU. This resulted in corrupted frames being transmitted. Now, injected MPDUs are transmitted as-is, without A-MSDU. The fix was verified with frame injection on MT7915 hardware, both with and without the injected frame being encrypted. If the hardware cannot do A-MSDU aggregation on MPDUs, this problem would also be present in the TX path where mac80211 does the 802.11 encapsulation. However, I have not observed any such problem when disabling IEEE80211_HW_SUPPORTS_TX_ENCAP_OFFLOAD to force that mode. Therefore this fix is isolated to injected frames only. The same A-MSDU logic is also present in the mt7921 driver, so it is likely that this fix should be applied there too. I do not have access to mt7921 hardware so I have not been able to test that.

2022-02-03mt76: mt7915: fix/rewrite the dfs state handling logicFelix Fietkau
Client mode on DFS channels was broken, because the old code was activating the DFS detector on radar channels while leaving it in CAC state. This was caused by making the decision based on the channel radar flag, instead of hw->conf.radar_enabled. In order to properly deal with the various corner cases, rip out the state handling code and replace it with something that's much easier to reason about.

2022-02-03mt76: sdio: honor the largest Tx buffer the hardware can supportSean Wang
We don't have to create a separate sdio.xmit_buf buffer for each queue. Instead, we just need to create one, reuse it across all queues to reduce memory consumption further. And then we should take it into account the actual the host and the device MMC capability to determine what the appropriate xmit_buf_size can be. Both MT7921S and MT7663 can support up to Tx FIFO size of 0x3fe00 which means the device can receive 511 blocks of block size 512 in a row from the host. So if the driver aggregates the frames as many as possible the the device can support, we can merge multiple MMC requests into a single one to get rid of the overhead of the handling and synchronizing in those unnecessary MMC requests and reduce the SDIO lock contention with the Bluetooth concurrent traffic and finally to have the higher bus utilization with less idle cycle. With the patch, it is helpful for WiFi to have steady throughput performance especially while running Bluetooth concurrently.

2022-02-03mt76: mt7915: set bssinfo/starec command when adding interfaceShayne Chen
bssinfo/starec disabled commands are sent during removing interface. However, if we don't set corresponding enabled commands before removing interface, the fw may enter an exception state due to some NULL structs. For example, the following commands can cause fw timeout in our newer chips: ifconfig wlan0/mon0 up ifconfig wlan0/mon0 down Fix this by setting enabled commands once interface added.

2022-02-03mt76: sdio: disable interrupt in mt76s_sdio_irqSean Wang
It is unnecessary to keep the interrupt enabled in mt76s_sdio_irq because the driver is already aware of the interrupt, schedules the mt76s_txrx_worker to handle the corresponding actions, and eventually, the interrupt would be enabled again when mt76s_txrx_worker finishes its work. So we can safely disable the interrupt in mt76s_sdio_irq as soon as possible to increase the CPU productivity by dropping the redundant interrupt triggers. Note that sdio lock acquired/released would be handled in sdio_irq_work at mmc driver so we don't take care in mt76s_sdio_irq at function driver.

2022-02-03mt76: mt7921e: fix possible probe failure after rebootSean Wang
It doesn't guarantee the mt7921e gets started with ASPM L0 after each machine reboot on every platform. If mt7921e gets started with not ASPM L0, it would be possible that the driver encounters time to time failure in mt7921_pci_probe, like a weird chip identifier is read [ 215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000 [ 216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110 or failing to init hardware because the driver is not allowed to access the register until the device is in ASPM L0 state. So, we call __mt7921e_mcu_drv_pmctrl in early mt7921_pci_probe to force the device to bring back to the L0 state for we can safely access registers in any case. In the patch, we move all functions from dma.c to pci.c and register mt76 bus operation earilier, that is the __mt7921e_mcu_drv_pmctrl depends on.
