For each netmap memory area (in this case you use only the global one):
- if_num must be >= of the total number of NIOCREGIF on the netmap memory
area. The default is 100 and it should be ok.
- Then you have to count how many TX and RX rings you use in total in all
the interfaces you NIOCREGIF'd

Not sure about what you mean. Until memory areas are in use the real values
(*_num, *_size) are not changed.
At NIOCREGIF time you can say what allocator you are interested in by
writing a non-zero id inside req.nr_arg2.

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 netma

hi
i am trying to assign more memory to netmap but it fails
i trace it to "netmap_mem_get_info" function ,this function changes my
defined memory size to 343019520 and i cant find the implementation of it
in the source code!
Thank you for any help you c
