Subject: [PATCH net-next] net: lan743x: PCI11010 / PCI11414 fix
Date: Fri, 27 May 2022 09:47:28 +0530 [thread overview]
Message-ID: <20220527041728.3257-1-Raju.Lakkaraju@microchip.com> (raw)
Fix the MDIO interface declarations to reflect what is currently supported by
the PCI11010 / PCI11414 devices (C22 for RGMII and C22_C45 for SGMII)
