This is a preliminary patch to introduce mt7921s support. Refactor mt7921_mcu_send_message to be sharable between mt7921s and mt7921e. Tested-by:

Rely on mcu_get_nic_capability to obtain Tx quota information for the SDIO device, get PHY capability, MAC address and then we can totally drop mt7921/eeprom.c and any unnecessary code. Noting that mt76_connac_mcu_get_nic_capability should be run before set flag MT76_STATE_MCU_RUNNING being set to setup the proper parameters like Tx quota control before the device is started to running.

The longer event such as the event for mcu_get_nic_capability would hold the data in paged fragment skb for the SDIO device so we turn the skb to be linearized skb before accessing it to reuse the same event parser betweem mt7921s and mt7921e. Tested-by:

This is a preliminary patch to introduce mt7921s support. make dma.c be used dedicately for mt7921e. by moving out mt7921_tx_cleanup from dma.c to mcu.c and then renaming mt7921_tx_cleanup to refect the exact thing the function actually does. Finally, dma.c totally become pcie specific one, only needed to be compiled only when CONFIG_MT7921E is enabled. Tested-by:

Avoids false positive on detecting frags or encrypted mgmt frames Signed-off-by: -
Xing Song authored
When received frame is decryped by hardware, CCMP PN is checked by mt76. When management frame protection (IEEE 802.11w) is used, we must use a separate counter for tracking received CCMP packet number for the management frames. The previously used counter was shared with data frames and that can cause problems in detecting replays incorrectly for robust management frames. Add a new counter just for robust management frames to avoid this issue. Signed-off-by:
