+=== LinuxKPI 802.11 Wireless Update
+
+Contact: Bjoern A. Zeeb <[email protected]> +

+
+With multiple wireless projects ongoing, this report focuses on the efforts using permissively licensed Linux wireless drivers mostly unmodified on FreeBSD.
+The currently supported drivers are man:iwlwifi[4], man:rtw88[4], and man:rtw89[4].
+
+The man:rtw88[4] driver was made to work (associate) again (link:https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=283142[Bugzilla PR#283142]).
+In addition, thanks to the massive help debugging and testing by the community, the cause for leaking memory got resolved (link:https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=283903[Bugzilla PR#283903]).
+
+Tunables to selectively control HT and VHT support in man:rtw88[4], and man:rtw89[4] were added.
+HW crypto offload was enabled by default for CCMP.
+It turns out that a lot of users are still using TKIP.
+Work is in on the way to support this and will hopefully land early in Q2.
+
+HT (11n) and VHT (11ac) support are now also compiled in by default for the LinuxKPI based drivers.
+The drivers and entire framework changes were merged from main to stable/14 so both branches have the same level of support.
+
+People installing firmware using man:fwget[8] will get HT and VHT automatically enabled for man:iwlwifi[4] 2200 (mostly AX200), AX210, and BE200 chipset generations.
+Older man:iwlwifi[4] chipset generations, man:rtw88[4], and man:rtw89[4] will need extra work in LinuxKPI or the driver to provide working support.
+
+It was announced that man:iwlwififw[4] will follow man:rtw88[4], and man:rtw89[4] firmware and be removed from the base system in April 2025 for both main and stable/14 in favor of the ports based solution and man:fwget[8] support (link:https://lists.freebsd.org/archives/freebsd-stable/2025-March/002763.html[Announcement]).
