Subject: [PATCH net-next v3 25/26] switchdev: convert swdev_fib_ipv4_add/del over to swdev_port_obj_add/del
From: Scott Feldman <sfeldma@...il.com>
The IPv4 FIB ops convert nicely to the swdev objs and we're left with only
four swdev ops: port get/set and port add/del. Other objs will follow, such
as FDB. So go ahead and convert IPv4 FIB over to swdev obj for consistency,
anticipating more objs to come.
