The name PADDING seems rather risky, collisions will be likely.
OVS_KEY_ATTR_PADDING maybe?
But maybe we don't need to define this special value and bake it into
the uAPI, why can't we add something like this to the kernel header
(i.e. include/linux/openvswitch.h):
/* Insert a kernel only KEY_ATTR */
#define OVS_KEY_ATTR_TUNNEL_INFO __OVS_KEY_ATTR_MAX
#undef OVS_KEY_ATTR_MAX
#define OVS_KEY_ATTR_MAX __OVS_KEY_ATTR_MAX
