As originally proposed in [1], the ath12k driver was re-architected in the ath12k-ng branch to separate the logic specific to 802.11be (Wi-Fi 7) from the core logic. This separation will allow ath12k to also support 802.11bn (Wi-Fi 8) in the future. Now merge this into ath-next. Many thanks to everyone who worked on this re-architecture. Special thanks to Vasanthakumar Thiagarajan and Baochen Qiang who reviewed every patch, and to Ripan Deuri for the ath12k-ng => ath-next merge conflict resolution.
