====================
wireless-next patches for v6.2

Third set of patches for v6.2. mt76 has a new driver for mt7996 Wi-Fi 7
devices and iwlwifi also got initial Wi-Fi 7 support. Otherwise
smaller features and fixes.

Major changes:

ath10k
 - store WLAN firmware version in SMEM image table

mt76
 - mt7996: new driver for MediaTek Wi-Fi 7 (802.11be) devices
 - mt7986, mt7915: enable Wireless Ethernet Dispatch (WED) offload support
 - mt7915: add ack signal support
 - mt7915: enable coredump support
 - mt7921: remain_on_channel support
 - mt7921: channel context support

iwlwifi
 - enable Wi-Fi 7 Extremely High Throughput (EHT) PHY capabilities
 - 320 MHz channels support
