Subject: [PATCH net-next v6 5/6] dsa: lan9303: Port 0 is xMII port
Date: Mon, 9 Jan 2023 15:18:48 -0600	[thread overview]
Message-ID: <20230109211849.32530-6-jerry.ray@microchip.com> (raw)
In-Reply-To: <20230109211849.32530-1-jerry.ray@microchip.com>

In preparing to move the adjust_link logic into the phylink_mac_link_up
api, change the macro used to check for the cpu port. In
phylink_mac_link_up, the phydev pointer passed in for the CPU port is
NULL, so we can't keep using phy_is_pseudo_fixed_link(phydev).
