Zeeb <bz@FreeBSD.org> AuthorDate: 2024-05-22 02:24:51 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2024-06-12 13:58:36 +0000 LinuxKPI: 802.11: change teardown order to avoid iwlwifi firmware crash= es While the previous order worked well for iwlwifi 22000 and later chipse= ts (AXxxx, BE200), earlier chipsets had trouble and ran into firmware cras= hes. Change the teardown order to avoid these problems. The inline comments in lkpi_sta_run_to_init() (and lkpi_disassoc()) try to document the new order and also the old problems we were seeing (too early sta removal or silent non-removal) leading to follow-up problems. There is a possible further problem still lingering but a lot harder to trigger (see comment in review) and likely related to some other doings so we'll track it separately.
