[dpdk-dev,v9,5/7] mbuf: add a timestamp to the mbuf for latencystats
Checks
Commit Message
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.
