Yes, this is a problem. But it is a bug not something that needs a deprecation
notice.  The DPDK has avoided using typedefs for port, queue, lcore, and socket.
With socket_id there is the need to represent SOCKET_ID_ANY which is -1.



Please file a bugzilla entry instead.
Looking at code, there a few places doing using uint8_t which will work since
no cpu at present supports that many numa nodes. Should probably be a compile
assert for that though.
