> Currently, in the case to use bitmap as resource allocator, after
> bitmap creation, all the bitmap bits should be set to indicate the
> bit available. Every time when allocate one bit, search for the set
> bits and clear it to make it in use.
>
> Add a new rte_bitmap_init_with_all_set() function to have a quick
> fill up the bitmap bits.
>
> Comparing with the case create the bitmap as empty and set the bitmap
> one by one, the new function costs less cycles.
