The branch stable/13 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=266cae8062643bd8e54f3dd34904fe4ff38d017a commit 266cae8062643bd8e54f3dd34904fe4ff38d017a Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2022-02-17 00:15:56 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2022-02-20 16:25:49 +0000 LinuxKPI: 802.11 advertise full offload scanning based on hw_scan only We disabled hw_scan for drivers not advertising SINGLE_SCAN_ON_ALL_BANDS. Do not depend on this hw flag to set IEEE80211_FEXT_SCAN_OFFLOAD for net80211 as otherwise scanning will never work. Long-term we probably want to re-think how we do/integrate hw_scan better in net80211.
