Subject: [PATCH 1/4] mt76: mt7615: add sta_rec with EXTRA_INFO_NEW for the first time only
Date:   Fri, 24 Jun 2022 21:12:57 +0200
Message-Id: <20220624191300.52766-1-nbd@nbd.name>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Set EXTRA_INFO_NEW for the first time only to prevent adding the same
starec entry, otherwise the entry might be removed in fw.
