From 0bc47057b54b73e5f6d36bfc7c5c96e15be1f221 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 18 Jun 2021 13:41:40 +0300 Subject: [PATCH] mac80211: conditionally advertise HE in probe requests While building probe requests, only enable HE capability if there are actually any channels in the band with HE enabled, otherwise we're not really capable. We're doing the same in association requests, so doing it here makes it consistent. This also makes HE not appear available if it isn't due to regulatory constraints.
