Isn't there a collision to have a SWITCHDEV_OBJ_IPV4_FIB enum and a
SWITCHDEV_OBJ_IPV4_FIB macro?
Maybe switchdev will support not only port-objects, but also switch chip
objects, so would it be good to make the distinction between them? e.g.:
* struct switchdev_obj_port_vlan
* SWITCHDEV_OBJ_ID_PORT_VLAN
* SWITCHDEV_OBJ_PORT_VLAN(obj)
* ...
What do you think?

This is indeed nice to have this typed.

I went with the void * way in order to pass minimalist structures to
drivers, so they can do whatever with them (memset, etc.), safely.
I also plan to use them for generic debugfs functions to carry the
content of the switch hardware tables.
Otherwise, given the comments on the naming, I prefer this more typed
version.
Thanks,
