- Run mt7921_configure_filter hodling mt76 mutex
- Correct Txp programming in Txd
- Correct fw log to host command
- Correct eeprom offset definition
- Update rate adaption info report
- Remove unused code and fields in struture
- Split the previous driver into several patches for easy review

v4:
- introduce sched scan support
- introduce 802.11 PS support in sta mode
- introduce support for hardware beacon filter
- introduce beacon_loss mcu event
- introduce PM support
- refine sta_rec_phy and add sta_rec_ra_info
- remove incorrect mt7921_mcu_tx_config member
- fix erroneous endianness conversion in mt7921_tx_complete_skb()
- fix endianness warning in mt7921_get_wtbl_info()
- fix endianness warnings in mt7921_mcu_sta_tlv()
- remove unused code in mt7921_mcu_send_message

Subject: [PATCH -next v4 02/13] mt76: mt7921: add MCU support

From: Sean Wang <[email protected]>

MT7921 contains a microprocessor with which the host can use command/event
to communicate to implement offload features such as establish connection,
hardware scan and so on. The host has to download the ROM patch, RAM
firmware and finally activate the MCU to complete the MT7921
initialization.

Subject: [PATCH -next v4 13/13] mt76: mt7921: introduce PM support

From: Sean Wang <[email protected]>

Introduce suspend/resume and WoW (Wake-on-WoWLAN) support to mt7921
driver to allow remote wakeu-up from the suspend state.

Implicit conversion from enumeration type 'enum mt76_mcuq_id' to
different enumeration type 'enum mt76_txq_id'

Should be enum mt76_mcuq_id

This was copied/pasted my wrong flow from mt7915 so I guess BIP_CMAC_128
cannot work. I've fixed this recently for mt7915. You may take a look at
https://patchwork.kernel.org/project/linux-wireless/patch/fc[email protected]mediatek.com/

Or, fallback to sw version

Just a quick look. Seem some unused functions (used by mt7915) are
exported here. e.g. mt7921_mcu_get_rx_rate()

Why not put mac.h into this patch?

Moreover, hardware cannot add LLC-SNAP when skb->data_len is 0, which
causes Tx stuck. We found this case happened on mt7915 (station mode)
quality test with few packets whose skb->len = 14

So,https://github.com/nbd168/wireless/commit/6b6605e4061c94c9909ff82acc0e02bfd3a8d40e

I remember mcu.c would refer to something in mac.h but it seems better move mac.h to here.

We'll add the fixes in the next version including mcu one you suggested in the other mail thread.

Happy new year
