====================
wireless-drivers-next patches for v5.8

First set of patches for v5.8. Changes all over, ath10k apparently
seeing most new features this time. rtw88 also had lots of changes due
to preparation for new hardware support.

In this pull request there's also a new macro to include/linux/iopoll:
read_poll_timeout_atomic(). This is needed by rtw88 for atomic
polling.

Major changes:

ath11k

* add debugfs file for testing ADDBA and DELBA

* add 802.11 encapsulation offload on hardware support

* add htt_peer_stats_reset debugfs file

ath10k

* enable VHT160 and VHT80+80 modes

* enable radar detection in secondary segment

* sdio: disable TX complete indication to improve throughput

* sdio: decrease power consumption

* sdio: add HTT TX bundle support to increase throughput

* sdio: add rx bitrate reporting

ath9k

* improvements to AR9002 calibration logic

carl9170

* remove buggy P2P_GO support

p54usb

* add support for AirVasT USB stick

rtw88

* add support for antenna configuration

ti wlcore

* add support for AES_CMAC cipher

iwlwifi

* support for a few new FW API versions

* new hw configs
