Zeeb <bz@FreeBSD.org> CommitDate: 2023-10-04 15:19:18 +0000 LinuxKPI: 802.11: improve lkpi_ic_vap_delete() Changing the order of cleanup in lkpi_ic_vap_delete() will avoid firmware crashes or a direct panic as observed as ieee80211_vap_detach() will do most cleanup for us and get us into the correct state. Calling mo_stop() in lkpi_ic_vap_delete() seems to stop the problem that further VAPs could not be created (error 17) after the first one being destroyed.
