From: Scott Feldman Date: Sun, 10 May 2015 16:48:06 +0000 (-0700) Subject: switchdev: convert fib_ipv4_add/del over to switchdev_port_obj_add/del X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=58c2cb16b116d7feace621bd6b647bbabacfa225;p=linux-beck.git switchdev: convert fib_ipv4_add/del over to switchdev_port_obj_add/del The IPv4 FIB ops convert nicely to the switchdev objs and we're left with only four switchdev ops: port get/set and port add/del. Other objs will follow, such as FDB. So go ahead and convert IPv4 FIB over to switchdev obj for consistency, anticipating more objs to come.
