Zeeb <bz@FreeBSD.org> AuthorDate: 2023-10-26 20:55:59 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2023-11-03 21:08:04 +0000 net80211: add ieee80211_add_vhtcap_ch() Add an implementation of ieee80211_add_vhtcap() which works based on information derived from the vap (and possibly channel/band but we do not support that yet in net80211). This is needed for scans request information in LinuxKPI at times before we have a BSS.
