[dpdk-dev] [RFC PATCH 05/14] mbuf: rename in_port to just port

[Bruce Richardson <bruce.richardson@intel.com>]

In some cases we may want to tag a packet for a particular destination
or output port, so rename the "in_port" field in the mbuf to just "port"
so that it can be re-used for this purpose if an application needs it.
