mac80211: skip disabled channels in VHT check
The patch "40a11ca mac80211: check if channels allow 80 MHz for VHT probe requests" considered disabled channels as VHT enabled, and mistakenly sent out probe-requests with the VHT IE. Signed-off-by: Arik Nemtsov <arikx.nemtsov@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
