While some devices update their own clock info to provide current time,
mlx5dv part of libibverbs already handles this and also converts any
raw counter cycle to nanoseconds.

Existing ethdev functions can read/write time from/to device but
they're all related to timesync and none of them can translate a raw
counter in real time unit which is useful in a pdump application.
A new API is required because the conversion is derived from dev
clock in
aders.

net/mlx5: add timestamp-to-ns converter from libibverbs
ethdev: add API to convert raw timestamps to nsec
Vivien Didelot (1):
net/pcap: support hardware Tx timestamps

additional alarm thread.
As a first step, pass the mbuf to the timestamp calculation function
since mbuf->port and mbuf->timestamp would be needed, and add a TODO
note. No functional changes.

nanosecond timeval addition. This also ensures that the precision
reported by capinfos is nanoseconds (9).
