The second chain value is 0 if the second chain is disabled, which
would make the reported signal strength 0 as well.

Port mt76x02_check_tx_hang watchdog from vendor driver in order to
perform a device reset when tx mac/dma logic hangs. Tx mac/dma stuck
has been observed when the device is heavy loaded or in a noisy
environment. Moreover introduce wdt delayed work in order to run
tx_hang watchdog. For the moment run mt76x02_check_tx_hang watchdog
just on mt76x2 devices since the issue has not been observed on mt76x0
driver yet

Do not set bw variable to zero for legacy rates since it is already
initialized to zero. Moreover set nss to 1 just for legacy rates
since nss will be properly set for VHT/HT rates

Ported from the reference driver. Should fix compliance with ETSI
regulatories on preventing transmission while energy detect values
are above the threshold.
The code has been tested using an ath9k device running tx99 as
noise generator

On new mt76 chips, phy mode is configured by last 3 bits
of rate value. Hence OFDM bit is marked by 0x2000
instead of 0x4000.

Protection for HT and VHT traffic is defined by HT operation element

that no tx related spinlocks are taken during the ieee80211_tx_status call

MODULE_FIRMWARE() is used in usb_mcu.c and provided by linux/module.h,
but this header file is not directly included. This causes problems in
backports with some kernel versions.
Add the missing include.

Some mt7603e chip has empty efuse data.
In this case driver will crash due to dereferencing NULL pointer.
The mt7603_eeprom_load will return success directly if the chip has no efuse
data and dev->mt76.otp.data is left empty, i.e. NULL pointer.
The mt7603_eeprom_init will then try to dereference dev->mt76.otp.data
without checking its value.
This patch adds a check around these codes to prevent kernel panic.

It is not necessary to time the start of the queue in software, the hardware
already does that for us.
Move all processing into the pre-tbtt tasklet to get rid of a race condition
that could happen when the pre-tbtt tasklet takes too long
