Subject: [PATCH 01/66] mt76: round up length on mt76_wr_copy

When beacon length is not a multiple of 4, the beacon could be sent with
the last 1-3 bytes corrupted. The skb data is guaranteed to have enough
room for reading beyond the end, because it is always followed by
skb_shared_info, so rounding up is safe.
All other callers of mt76_wr_copy have multiple-of-4 length already.

Subject: [PATCH 08/66] mt76: mt7615: clean up FWDL TXQ during/after firmware
 upload

Since we don't clean that tx queue from the tx tasklet, we need to do it
after the firmware upload is done. This patch also adds a cleanup step during
the upload, to help reclaim memory faster.

Fixes unprocessed queued frames eating up memory  long after the firmware
upload has already completed

Subject: [PATCH 11/66] mt76: mt7615: introduce mt7615_mcu_send_ram_firmware
 routine

Add mt7615_mcu_send_ram_firmware routine since mt7615_load_ram runs the
same code to send ram firmware to cr4 and n9 mcus. Moreover rename
gen_dl_mode in mt7615_mcu_gen_dl_mode.
This patch does not introduce any behaviour change, it is just code
refactor.

 update

These values must be initialized to zero, otherwise the hardware could
reuse previous values, especially the rate index

Subject: [PATCH 15/66] mt76: mt7615: sync with mt7603 rate control changes

- Store the previous and current rate set in the driver + the TSF value
  at the time of the switch.
- Use the tx status TSF value to determine which rate set needs to be used
  as reference.
- Report only short or long GI rates for a single status event, not a mix.
- The hardware reports the last used rate index. Use it along with the
  retry count to figure out what rate was used for the first attempt.
- Use the same retry count value for all rate slots to make this calculation
  work.
- Derive the probe rate from the current rateset instead of the skb cb
- Do not wait for a status report for the probe frame before removing the
  probe rate from the rate table. Do it immediately after it was referenced
  in a tx status report.
- Use the first half of the first rate retry budget for the probe rate
  in order to avoid using too many retries on that rate
- Switch from lower rates to higher rates more conservatively
- enable hardware rate up/down selection

Subject: [PATCH 17/66] mt76: mt7615: fix using VHT STBC rates

The hardware expects MT_TX_RATE_NSS to be filled with the number of
space/time streams. For non-STBC rates, this is equal to nss.
For 1-stream STBC, this needs to be set to 2.
This is relevant for VHT rates only, on HT, the value is derived from MCS
internally.

Subject: [PATCH 32/66] mt76: mt7615: add set_key_cmd and mt76_wcid to
 mt7615_mac_wtbl_set_key signature

Introduce set_key_cmd and mt76_wcid pointer to mt7615_mac_wtbl_set_key
signature and do not set key to NULL if cmd is DISABLE_KEY.
This is a preliminary patch to add BIP_CMAC_128 hw support to mt7615
driver

Subject: [PATCH 43/66] mt76: mt7615: rework locking scheme for
 mt7615_set_channel

As already done for mt7603 driver, move mt76.mutex lock inside
mt7615_set_channel since we need to grab mt76.mutex in mt7615_mac_work.
This is a preliminary patch to add Smart Carrier Sense (SCS) support

Subject: [PATCH 46/66] mt76: mt76x02: do not copy beacon skb in
 mt76x02_mac_set_beacon_enable

Do not copy beacon skb in mt76x02_mac_set_beacon_enable for usb devices
since it will be done in mt76x02_update_beacon_iter. Moreover squash
mt76x02_mac_set_beacon_enable and __mt76x02_mac_set_beacon_enable since
the latter is run just by mt76x02_mac_set_beacon_enable

Subject: [PATCH 47/66] mt76: mt76x02u: enable multi-vif support

Enable multi-interface support for mt76x02u driver. For the moment
allow max two concurrent interfaces in order to preserve enough room
for ps traffic since we are using beacon slots for it.
I have successfully tested the following configuration:
- AP + STA
- AP0 + AP1

Subject: [PATCH 55/66] mt76: add default implementation for
 mt76_sw_scan/mt76_sw_scan_complete

Introduce a default implementation for mt76_sw_scan and
mt76_sw_scan_complete in mt76 module and remove duplicated code
since most of the drivers share the same implementation

Subject: [PATCH 56/66] mt76: mt7615: apply calibration-free data from OTP

MT7615 chips usually come pre-calibrated, even when used on embedded boards.
In that case, the on-flash EEPROM data needs to be merged with some data
from OTP ROM.
Run this merge if the external EEPROM data is valid and OTP has valid fields.
