Hi, You're right, we'll try to add more details. In any case, buf_size, ring_size and if_size are the sizes in bytes of each buffer, ring and netmap_if (control data structure), respectively. So the maximum amount of slots for each ring is ring_size/16, as 16 is the size in bytes of struct netmap_slot.
On the other side, buf_num, ring_num and if_num are the total number of biffers, rings and netmap_if objects in each netmap memory area (aka "allocator"). By default there is a single memory area used by all the hardware NICs and a separate memory area for each VALE port. This is already configurable, however.
