From 1fe94f542e66b5de526233762ed528e7d3b66ff9 Mon Sep 17 00:00:00 2001 From: Arun Ramadoss Date: Fri, 17 Jun 2022 14:12:55 +0530 Subject: [PATCH] net: dsa: microchip: move get_phy_flags & mtu to ksz_common This patch assigns the get_phy_flags & mtu hook of ksz8795 and ksz9477 in dsa_switch_ops to ksz_common. For get_phy_flags hooks,checks whether the chip is ksz8863/kss8793 then it returns error for port1.
