From 9735f2d2fe2c0078684c1ed17e53b7640af1c21b Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 13 Dec 2018 11:54:48 +0000 Subject: [PATCH] mlxsw: spectrum_router: Generalize mlxsw_sp_netdevice_router_port_event() Prepare mlxsw_sp_netdevice_router_port_event() for handling of NETDEV_PRE_CHANGEADDR. Split out the part that deals with the actual changes and call it for the two events currently handled.
