Since the other pseudorandom functions are called rand, such a function should be named rte_rand_bytes().

Absolutely not! We need a fast pseudorandom number generator in DPDK.
If anything, we could consider renaming the functions and header file to reflect that they are pseudorandom number generators, and not (cryptographically) random generators. That would cause an API/ABI breakage, so it's probably not going to happen. ;-)
