121  * e.g.
122  * stats_registrations[IDX_INTERFACE_SIMPLE_COUNTERS] refers to a pool

130  * ie
131  * 0 == pool_elts(stats_registrations[IDX_INTERFACE_SIMPLE_COUNTERS]

133  * then there is no need to process INTERFACE_SIMPLE_COUNTERS

135  * Note that u32 item = ~0 is the simple case for ALL interfaces or fibs.
