+  The number of BSN output monitor in the FN instances is 3 and is oke in MMM, SOPC. However:
+  -r 0 Oke
+  -r 1,2 yield timeout = 1 and sync_cnt /= 0, others all 0, possibly because dp_offload_tx_src_out_arr and tr_10GbE_snk_in_arr have no sync ?
+  -r 3 Oke, all zeros because only 2:0 are connected
+  -r 4 Oke, yields address error, because ceil_log2(3) = 4
