No, it doesn't:
from libmlx4/src/verbs.c:
static int align_queue_size(struct ibv_context *context, int size, int spare)
{
int ret;
/*
* If someone asks for a 0-sized queue, presumably they're not
* going to use it. So don't mess with their size.
*/
if (!size)
return 0;
Note that if the requested size is zero, the function returns zero.
