Subject: [PATCH net-next v1 6/6] net: dsa: microchip: ksz9477: make switch MAC address configurable
Date: Thu, 20 Jul 2023 15:25:56 +0200	[thread overview]
Message-ID: <20230720132556.57562-7-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20230720132556.57562-1-o.rempel@pengutronix.de>

The switch MAC address is used for sending pause frames and for Wake on Magic
Packet. So, make use of local-mac-address property in the switch node
root and configure it in the HW.
