109 * IDX_xxxx_COUNTER generated for each streaming
110 * stat a client can register for. (see stats.reg)
112 * The values in the vector refer to pools.
114 * The pool is of type vpe_client_stats_registration_t
116 * This typedef consists of:
118 * u32 item: This is the instance of the IDX_xxxx_COUNTER a
119 * client is interested in.
120 * vpe_client_registration_t *clients: The list of clients interested.
123 * stats_registrations[IDX_INTERFACE_SIMPLE_COUNTERS] refers to a pool
124 * containing elements:
126 * u32 item = sw_if_index1
127 * clients = ["clienta","clientb"]
129 * When clients == NULL the pool element is freed. When the pool is empty
132 * 0 == pool_elts(stats_registrations[IDX_INTERFACE_SIMPLE_COUNTERS]
134 * then there is no need to process INTERFACE_SIMPLE_COUNTERS
136 * Note that u32 item = ~0 is the simple case for ALL interfaces or fibs.
