commit f8612fa7e07cf2a8076d8ee8cbdd8ab19dcd8a95 Author: Bjoern A. Zeeb <[email protected]> AuthorDate: 2021-12-26 18:52:51 +0000 Commit: Bjoern A. Zeeb <[email protected]> CommitDate: 2021-12-30 18:27:45 +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.
