- in the ip_newid macro, we do "htons(V_ip_id++))" if we do not use

In multi core systems, we may emit successive packets with the same id.
Will using a mutex or an atomic macro fix this issue when incrementing the
V_ip_id ?
It will, but it'll ping-pong between multiple cores and slow things
down at high pps.
Hi,
Maybe we can have the V_ip_id per CPU and use the lower 8-bits as random
CPU core number?
OK?
