Subject: [PATCH v2 6/6] ARM: boards: skov-imx6: assigned separate MAC address to LAN2
Date: Thu,  3 Nov 2022 14:13:51 +0100	[thread overview]
Message-ID: <20221103131351.2059683-6-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20221103131351.2059683-1-o.rempel@pengutronix.de>

We have two external ports and different MAC addresses on each port. So,
assign different MAC to the LAN2. The address on LAN1 is the
system default address.
