e5243352a4 wifi: mt76: mt7915: reduce the number of command retries 
The need to retry a command is really uncommon. Reduce the retries to 1 to
speed up recovery from firmware issues.

8ad8b8c2dc wifi: mt76: mt7925: replace zero-length array with flexible-array member 
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1],
introduced in C99:

struct foo {
	int stuff;
	struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last, which is beneficial
to cultivate a high-quality code.[2]

This issue was found with the help of Coccinelle.

57af267d2b wifi: mt76: mt7915: add module param to select 5 GHz or 6 GHz on MT7916 
Due to a limitation in available memory, the MT7916 firmware can only
handle either 5 GHz or 6 GHz at a time. It does not support runtime
switching without a full restart.

On older firmware, this accidentally worked to some degree due to missing
checks, but couldn't be supported properly, because it left the 6 GHz
channels uncalibrated.
Newer firmware refuses to start on either band if the passed EEPROM
data indicates support for both.

Deal with this limitation by using a module parameter to specify the
preferred band in case both are supported.

f1b1e133a7 wifi: mt76: mt76u_vendor_request: Do not print error messages when -EPROTO 
When initializing the network card, unplugging the device will
trigger an -EPROTO error, resulting in a flood of error messages
being printed frantically.

The exception is printed as follows：

         mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
         mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
         ...

It will continue to print more than 2000 times for about 5 minutes,
causing the usb device to be unable to be disconnected. During this
period, the usb port cannot recognize the new device because the old
device has not disconnected.

There may be other operating methods that cause -EPROTO, but -EPROTO is
a low-level hardware error. It is unwise to repeat vendor requests
expecting to read correct data. It is a better choice to treat -EPROTO
and -ENODEV the same way.

Similar to commit 9b0f100c19 ("mt76: usb: process URBs with status
EPROTO properly") do no schedule rx_worker for urb marked with status
set  -EPROTO. I also reproduced this situation when plugging and
unplugging the device, and this patch is effective.

Just do not vendor request again for urb marked with status set -EPROTO.

f21b77cb55 wifi: mt76: mt7915: Fix mesh scan on MT7916 DBDC 
commit c4f0755823 ("wifi: mt76: mt7915: fix command timeout in AP stop
period") changes the behavior of mt7915_bss_info_changed() in mesh mode
when enable_beacon becomes false: it calls mt7915_mcu_add_bss_info(...,
false) and mt7915_mcu_add_sta(..., false) while the previous code
didn't.  These sends mcu commands that apparently confuse the firmware.

This breaks scanning while in mesh mode on AsiaRF MT7916 DBDC-based cards:
scanning works but no mesh frames get sent afterwards and the firmware
seems to be hosed.  It breaks on MT7916 DBDC but not on MT7915 DBDC.
