Without it I'm getting an error of missing file on the new include, I can replace it with an ifdef similar to what rte_ip.h has and loose the dependency:

#ifdef RTE_EXEC_ENV_WINDOWS
#include <ws2tcpip.h>
#else
#include <netinet/in.h>
#include <netinet/ip.h>
#include <netinet/ip6.h>
#endif

however I think it's better to remove OS includes, unless there is an issue with adding 'net' as dependency.
