Subject: [PATCH 17/31] mac80211: always include HE 6GHz capability in probe request
Date: Fri, 18 Jun 2021 13:41:42 +0300	[thread overview]
Message-ID: <iwlwifi.20210618133832.25ee4a54a7d0.I8cebd799c85524c8123a11941a104dbdefc03762@changeid> (raw)
In-Reply-To: <20210618104156.747775-1-luca@coelho.fi>

From: Johannes Berg <johannes.berg@intel.com>

If HE/6GHz is available (thus we consider dot11HE6GOptionImplemented
to be true), then always include the corresponding capability in the
probe request as required by the spec.
