Kalle Valo says:
====================
wireless-drivers-next patches for v5.13
Second set of patches for v5.13. A lot of iwlwifi and mt76 patches
this time, and also smaller features and fixes all over.
mt76
* mt7915/mt7615 decapsulation offload support
* threaded NAPI support
* new device IDs
* mt7921 device reset support
* rx timestamp support
iwlwifi
* passive scan support for 6GHz
* new hardware support
wilc1000
* CRC support for SPI bus
====================
