bssinfo/starec disabled commands are sent during removing interface.
However, if we don't set corresponding enabled commands before
removing interface, the fw may enter an exception state due to
some NULL structs.
For example, the following commands can cause fw timeout in our newer
chips:
ifconfig wlan0/mon0 up
ifconfig wlan0/mon0 down
Fix this by setting enabled commands once interface added.

It is unnecessary to keep the interrupt enabled in mt76s_sdio_irq because
the driver is already aware of the interrupt, schedules the
mt76s_txrx_worker to handle the corresponding actions, and eventually,
the interrupt would be enabled again when mt76s_txrx_worker finishes its
work.
So we can safely disable the interrupt in mt76s_sdio_irq as soon as
possible to increase the CPU productivity by dropping the redundant
interrupt triggers.
Note that sdio lock acquired/released would be handled in sdio_irq_work
at mmc driver so we don't take care in mt76s_sdio_irq at function driver.

It doesn't guarantee the mt7921e gets started with ASPM L0 after each
machine reboot on every platform.
If mt7921e gets started with not ASPM L0, it would be possible that the
driver encounters time to time failure in mt7921_pci_probe, like a
weird chip identifier is read
[ 215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000
[ 216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110
or failing to init hardware because the driver is not allowed to access the
register until the device is in ASPM L0 state. So, we call
__mt7921e_mcu_drv_pmctrl in early mt7921_pci_probe to force the device
to bring back to the L0 state for we can safely access registers in any
case.
In the patch, we move all functions from dma.c to pci.c and register mt76
bus operation earilier, that is the __mt7921e_mcu_drv_pmctrl depends on.

Third set of patches for v5.17, and the final one if all goes well. We
have Specific Absorption Rate (SAR) support for both mt76 and rtw88.
Also iwlwifi should be now W=1 warning free. But otherwise nothing
really special this time, business as usual.
Major changes:
mt76
* Specific Absorption Rate (SAR) support
* mt7921: new PCI ids
* mt7921: 160 MHz channel support
iwlwifi
* fix W=1 and sparse warnings
* BNJ hardware support

====================
wireless-drivers-next patches for v5.17
Third set of patches for v5.17, and the final one if all goes well. We
have Specific Absorption Rate (SAR) support for both mt76 and rtw88.
Also iwlwifi should be now W=1 warning free. But otherwise nothing
really special this time, business as usual.
Major changes:
mt76
* Specific Absorption Rate (SAR) support
* mt7921: new PCI ids
* mt7921: 160 MHz channel support
iwlwifi
* fix W=1 and sparse warnings
* BNJ hardware support
* add new killer device ids
* support for Time-Aware-SAR (TAS) from the BIOS
* Optimized Connectivity Experience (OCE) scan support
rtw88
* hardware scan
* Specific Absorption Rate (SAR) support
ath11k
* qca6390/wcn6855: report signal and tx bitrate
* qca6390: rfkill support
* qca6390/wcn6855: regdb.bin support

Commit d068ca2ae2 ("codel: split into multiple files") moved all
Qdisc-related code to codel_qdisc.h, move the include of pkt_sched.h
as well.
This is similar to the previous commit, although we don't care as
much about incremental builds after pkt_sched.h was touched itself
it is included by net/sch_generic.h which is modified ~20 times
a year.
This decreases the incremental build size after touching pkt_sched.h
from 1592 to 617 objects.
Fix unmasked missing includes in WiFi drivers.

Fix the false positive suspend error that may occur on mt7921s
with enlarging mcu timeout value.
The reason why we have to enlarge mcu timeout from HZ / 3 to HZ is
we should consider the additional overhead caused by running
concurrently with btmtksdio (a MT7921 bluetooth SDIO driver) that
would compete for the same SDIO bus in process context to complete
the suspend procedure.

When the EEPROM data is stored on a MTD partition print an error message
when reading this MTD partition failed. This is currently happening
often in OpenWrt because the initial data was written with using a flash
driver which ignores the error detection data and now OpenWrt uses a
driver which checks it.
With this patch a better error message is shown:

commit 7f4b792031 ("mt76: mt7615: add ibss support") introduced IBSS
and commit f4ec7fdf7f ("mt76: mt7615: enable support for mesh")
meshpoint support.
Both used in the "get_omac_idx"-function:
if (~mask & BIT(HW_BSSID_0))
return HW_BSSID_0;
With commit d8d59f66d1 ("mt76: mt7615: support 16 interfaces") the
ibss and meshpoint mode should "prefer hw bssid slot 1-3". However,
with that change the ibss or meshpoint mode will not send any beacon on
the mt7622 wifi anymore. Devices were still able to exchange data but
only if a bssid already existed. Two mt7622 devices will never be able
to communicate.
This commits reverts the preferation of slot 1-3 for ibss and
meshpoint. Only NL80211_IFTYPE_STATION will still prefer slot 1-3.
Tested on Banana Pi R64.
