This could be 32-bit words on 32 bit architectures. Just an idea.

RTE bitset uses size_t to index the bits.
This means that it supports very large bitsets.

If it is not supposed to support more than 2^32 bits, it could use uint32_t for indexing.
I don't know if it make any practical difference.

With or without considering the above ideas, this library is a good addition to DPDK.
