With threaded NAPI, the rx handler function is no longer bound to the CPU that fired the interrupt, which significantly helps to spread the workload over multiple CPUs, especially when multiple devices are using threaded NAPI at the same time. Exclude the tx handler from threaded NAPI by using a separate dummy netdev. The work is small and short-lived enough that it makes more sense to run it in softirq instead of creating a dedicated thread Signed-off-by: -

As done for mt76_connac_mcu_alloc_wtbl_req, even if this is not a real bug since mt7915_mcu_alloc_wtbl_req routine can fails just if nskb is NULL, always check return value from mt7915_mcu_alloc_wtbl_req in order to avoid possible future mistake. Signed-off-by:

When operating two VAP on a MT7610 with encryption (PSK2, SAE, OWE), only the first one to be created will transmit properly encrypteded frames. All subsequently created VAPs will sent out frames with the payload left unencrypted, breaking multicast traffic (ICMP6 NDP) and potentially disclosing information to a third party. Disable GTK offloading and encrypt these frames in software to circumvent this issue. THis only seems to be necessary on MT7610 chips, as MT7612 is not affected from our testing. Signed-off-by:

Currently the expression ~nic_conf1 is always true because nic_conf1 is a u16 and according to 6.5.3.3 of the C standard the ~ operator promotes the u16 to an integer before flipping all the bits. Thus the top 16 bits of the integer result are all set so the expression is always true. If the intention was to flip all the bits of nic_conf1 then casting the integer result back to a u16 is a suitabel fix. Interestingly static analyzers seem to thing a bitwise ! should be used instead of ~ for this scenario, so I think the original intent of the expression may need some extra consideration.

Although FW crash logs are already supported for dumping in driver, the logs may not be sufficient to analyze field issues. To improve this part, we add a support to dump FW memory. When driver receives FW crash notifications, driver uses DDMA, which is a HW ability, to copy specified FW memory to FW fifo. Driver can then dump these information from FW fifo. With this support, not only FW crash log but also specified FW memory will be dumped while FW crash. Besides, specified registers are also dumped. This feature is implemeted on 8822C first due to difference of FW layouts between ICs. In addition, we add a debugfs to trigger FW crash. It can simulate the process of crash, dump and reset. Through it, we can also check if a reset is ongoing. Signed-off-by:
