Subject: [PATCH v2 00/10] wifi: mt76: mt7925: fix connection and throughput issues

From: Ming Yen Hsieh <[email protected]>

Hi,

Recently, we have some tests on the mt7925 driver and find a number of
potential connection bugs and throughput issues. This patchset contains
bugfixes and cleanups for these issues.

Thanks,
Yen.

v2:
1. [PATCH 04/10] wifi: mt76: mt7925: fix wmm queue mapping
a. change mq_to_aci[] definition from "static" to "static const".
2. Resend v2 patchset for wrong patch version submit.

Subject: [PATCH v2 07/10] wifi: mt76: mt7925: fix the wrong header translation config

From: Ming Yen Hsieh <[email protected]>

The header translation config should set to broadcast and unicast
cases correctly, not only unicast case. And also remove the cmds
of wtbl (wlan table) series, because these MCU commands have
already been replaced by other commands in mt7925.

There's a race between driver and fw on some tx/rx control registers
when setting ifs, which will cause accidental hw queue pause problems.
Avoid this by setting ifs time with bss_info mcu command.

Subject: [PATCH v2 06/10] wifi: mt76: mt7925: fix WoW failed in encrypted mode

From: Ming Yen Hsieh <[email protected]>

When in suspend mode, WoW (Wake-on-WLAN) fails to wake the system remotely
due to incorrect encryption mode settings. For the new mt7925 chipset, the
old STA_REC_KEY_V2 command will send incorrect parameters to the firmware.
Therefore, STA_REC_KEY_V3 has been introduced as a replacement for it.
