[PATCH v10 5/7] mbuf: add a timestamp to the mbuf for latencystats

From: Remy Horton <hidden>
Date: 2017-02-03 10:33:47
Subsystem: library code, the rest · Maintainers: Andrew Morton, Linus Torvalds

From: Harry van Haaren <redacted>

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.
