[dpdk-dev] [PATCH v9 5/7] mbuf: add a timestamp to the mbuf for latencystats

[Remy Horton <remy.horton@intel.com>]

From: Harry van Haaren <harry.van.haaren@intel.com>

This commit adds a uint64_t to the mbuf struct,
allowing collection of latency and jitter statistics
by measuring packet I/O timestamps. This change is
required by the latencystats library.
