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.

Use set_rts_threshold calback to enable/disable threshold only for
legacy traffic.
Protection for HT and VHT traffic is defined by HT operation element
and it's provided by remote AP or by hostapd.

As already done for pcie code in commit 79d1c94c9c78 ("mt76: avoid
queue/status spinlocks while passing tx status to mac80211") make sure
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.

Sometimes during startup, the MCU response time can be quite long,
especially in newer versions. This change prevents false timeout errors

Should fix compliance with ETSI rules on preventing transmission while

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

Use PSE registers to loop back any pending tx packets for a client that
just went to sleep back into the MCU rx queue.
Re-queue those packets to the tx queue immediately after a client wakes up.

This makes it easier to loop powersave-filtered packets through the MCU queue
