The branch stable/13 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=38fff4bd94338441d77446c05e3ef11111915297 commit 38fff4bd94338441d77446c05e3ef11111915297 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2023-09-25 17:54:20 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-11-29 16:36:09 +0000 LinuxKPI: 802.11: fill regulatory_hint() with some life Start implementing regulatory_hint() using a .c file based allocation helper function so we could change structures in the future with better chances to keep compatibility. This sets wiphy->regd needed by various LinuxKPI based WiFi drivers.
