commit f8612fa7e07cf2a8076d8ee8cbdd8ab19dcd8a95
Author:     Bjoern A. Zeeb <bz@FreeBSD.org>
AuthorDate: 2021-12-26 18:52:51 +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.
