Subject: [PATCH 2/7] mt76: mt7615: add mt7615_mac_wtbl_addr routine
Date: Sat, 13 Jul 2019 17:09:02 +0200
Message-ID: <8ebcb9d6fe715a9a7683cd25250325c5a3d2ddb2.1563029769.git.lorenzo@kernel.org> (raw)
In-Reply-To: <cover.1563029769.git.lorenzo@kernel.org>

Introduce mt7615_mac_wtbl_addr rouinte to compute sta wtbl address.
This is a preliminary patch to update wtbl key directly from host
processor
