2021-12-19mt76: mt7921s: fix the device cannot sleep deeply in suspendSean Wang
According to the MT7921S firmware, the cmd MCU_UNI_CMD_HIF_CTRL have to be last MCU command to execute in suspend handler and all data traffic have to be stopped before the cmd MCU_UNI_CMD_HIF_CTRL starts as well in order that mt7921 can successfully fall into the deep sleep mode. Where we reuse the flag MT76_STATE_SUSPEND and avoid creating another global flag to stop all of the traffic onto the SDIO bus.

2021-12-19mt76: do not pass the received frame with decryption errorXing Song
MAC80211 doesn't care any decryption error in 802.3 path, so received frame will be dropped if HW tell us that the cipher configuration is not matched as well as the header has been translated to 802.3. This case only appears when IEEE80211_FCTL_PROTECTED is 0 and cipher suit is not none in the corresponding HW entry. The received frame is only reported to monitor interface if HW decryption block tell us there is ICV error or CCMP/BIP/WPI MIC error. Note in this case the reported frame is decrypted 802.11 frame and the payload may be malformed due to mismatched key.

2021-12-19Merge branch 'tc-action-offload'David S. Miller
Simon Horman says: ==================== allow user to offload tc action to net device Baowen Zheng says: Allow use of flow_indr_dev_register/flow_indr_dev_setup_offload to offload tc actions independent of flows. The motivation for this work is to prepare for using TC police action instances to provide hardware offload of OVS metering feature - which calls for policers that may be used by multiple flows and whose lifecycle is independent of any flows that use them. This patch includes basic changes to offload drivers to return EOPNOTSUPP if this feature is used - it is not yet supported by any driver.
