The branch main has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=6b4cac814e32f3b307720d6b880939fb1f21f3ac commit 6b4cac814e32f3b307720d6b880939fb1f21f3ac Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2021-12-26 18:52:51 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2021-12-27 18:47:25 +0000 LinuxKPI: add 802.11 compat code Add 802.11 compat code for mac80211 and to a minimal degree cfg80211. This allows us to compile and use basic functionality of wireless drivers such as iwlwifi. This is a constant work in progress but having it in the tree will allow others to test and more easy to track changes and avoid having snapshots no longer applying to branches.
