Subject: [RFC PATCH 07/14] wifi: rtl8xxxu: Add parameter macid to update_rate_mask
Date:   Wed, 22 Mar 2023 18:18:58 +0100
Message-Id: <20230322171905.492855-8-martin.kaistra@linutronix.de>
In-Reply-To: <20230322171905.492855-1-martin.kaistra@linutronix.de>

Precedence: bulk

The HW maintains a rate_mask for each connection, referenced by the
macid. Add a parameter to update_rate_mask and add the macid to the
h2c call in the gen2 implementation.

Also extend refresh_rate_mask to generate the macid in AP mode from
sta->aid.
