Zeeb <bz@FreeBSD.org> CommitDate: 2023-09-30 15:27:05 +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. The solution is not fully developed yet and one may not be able to create a new vap (lkpi_ic_vap_create may fail with error 17) afterwards. It is supposed to be a step towards more stability for now.
