The branch releng/14.0 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=6fcde966446505c70f95d95bf03bf4ae6b4ddfc4 commit 6fcde966446505c70f95d95bf03bf4ae6b4ddfc4 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2023-09-21 12:49:15 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-10-09 23:14:54 +0000 LinuxKPI: 802.11: setup a default link[0] and adjust related needs Setup more link_conf/deflink fields for vif/sta as are needed to allow us to work with the KPI bits in a non-MLO configuration. In lkpi_sta_scan_to_auth() set the bss_conf values before calling into the driver for chanctx setup/updates as certain values (e.g., beacon_int) need to be set before; we still call the MO function for the updates after to keep the expected workflow. Deal with the (to be dealt with otherwise later) net80211 ni swaps and update the addresses on the deflink as well as otherwise firmware will hit asserts or things will not work (e.g. indicating the peer is us).
