[PATCH net-next 0/6] net: switchdev: use specific switchdev_obj_*

[Vivien Didelot]

This patchset changes switchdev add, del, dump operations from this:

    int     (*switchdev_port_obj_add)(struct net_device *dev,
                                      struct switchdev_obj *obj,
                                      struct switchdev_trans *trans);
    int     (*switchdev_port_obj_del)(struct net_device *dev,
                                      struct switchdev_obj *obj);
    int     (*switchdev_port_obj_dump)(struct net_device *dev,
                                      struct switchdev_obj *obj);

to something similar to the notifier_call callback of a notifier_block:

    int     (*switchdev_port_obj_add)(struct net_device *dev,
                                      enum switchdev_obj_id id,
                                      const void *obj,
                                      struct switchdev_trans *trans);                                                             
    int     (*switchdev_port_obj_del)(struct net_device *dev,
                                      enum switchdev_obj_id id,
                                      const void *obj);
    int     (*switchdev_port_obj_dump)(struct net_device *dev,
                                       enum switchdev_obj_id id, void *obj,
                                       int (*cb)(void *obj));

This allows the caller to pass and expect back a specific switchdev_obj_*
structure (e.g. switchdev_obj_fdb) instead of the generic switchdev_obj one.

This will simplify pushing the callback function down to the drivers.

The first 3 patches get rid of the dev parameter of the dump callback, since it
is not always neeeded (e.g. vlan_dump) and some drivers (such as DSA drivers)
may not have easy access to it.

Patches 4 and 5 implement the change in the switchdev operations and its users.

Patch 6 extracts the inner switchdev_obj_* structures from switchdev_obj and
removes this last one.

Vivien Didelot (6):
  net: switchdev: remove dev in port_vlan_dump_put
  net: switchdev: move dev in switchdev_fdb_dump
  net: switchdev: remove dev from switchdev_obj cb
  net: switchdev: pass callback to dump operation
  net: switchdev: abstract object in add/del ops
  net: switchdev: extract struct switchdev_obj_*
