VPP API: Memory trace
if you plan to put a hash into shared memory, the key sum and key
equal functions MUST be set to constants such as KEY_FUNC_STRING,
KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process
which set up the hash won't have the same idea where the key sum and
key compare functions live in other processes.
