wifi: mt76: fix rx checksum offload on mt7615/mt7915/mt7921

2022-10-11T08:41:20Z

Checking the relevant rxd bits for the checksum information only indicates if the checksum verification was performed by the hardware and doesn't show actual checksum errors. Checksum errors are indicated in the info field of the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY by checking the extra bits as well. Those bits are only passed to the driver for MMIO devices at the moment, so limit checksum offload to those.

wifi: mt76: mt7921: move mt7921_rx_check and mt7921_queue_rx_skb in mac.c

2022-09-15T10:53:58Z

Since both mt7921_rx_check and mt7921_queue_rx_skb routines are used by all chipsets (mmio, usb and sdio), move them in mac.c and remove duplicated code. Signed-off-by: Lorenzo Bianconi Signed-off-by: Felix Fietkau

wifi: mt76: mt7921e: fix race issue between reset and suspend/resume

2022-09-15T10:53:57Z

It is unexpected that the reset work is running simultaneously with the suspend or resume context and it is possible that reset work is still running even after mt7921 is suspended if we don't fix the race issue. Thus, the suspend procedure should be waiting until the reset is completed at the beginning and ignore the subsequent the reset requests. In case there is an error that happens during either suspend or resume handler, we will schedule a reset task to recover the error before returning the error code to ensure we can immediately fix the error there.

mt76: mt7921: reduce the mutex lock scope during reset

2022-07-11T11:40:03Z

Reduce the mutex lock scope for reset to get rid of possible task hung e.g wpa_supplicant and to allow the user-space process to keep running during we need more retries to complete the reset.

mt76: do not use skb_set_queue_mapping for internal purposes

2022-07-11T11:40:03Z

Previously the code used skb_set_queue_mapping for management or non-bufferable powersave frames that need to be sent to a different hardware queue. This can confuse AQL, which expects the value to remain the same until the tx status report. The only place that currently uses the altered skb queue mapping is the txwi write function. Change the code to pass the hardware queue id as a function parameter instead. Signed-off-by: Felix Fietkau
