The branch stable/15 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=f28bc5e194777be6381976bd43826376d948ef12 commit f28bc5e194777be6381976bd43826376d948ef12 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2026-06-22 01:11:18 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2026-06-29 03:55:09 +0000 LinuxKPI: 802.11: track bandwidth/rx_nss change in lkpi_sta_sync_from_ni() In lkpi_sta_sync_from_ni() track the bandwidth and rx_nss at the beginning so at the end we can diff if they changed in order to generate the appropriate RC*CHNAGED flags for the (*link_sta_rc_update) downcall.
