The intention is to produce a pcap with nanosecond precision when
Rx timestamp offloading is activated on mlx5 NIC.
The packets forwarded by testpmd hold the raw counter but a pcap
requires a time unit. Assuming that the NIC clock is already synced
with external master clock, this patchset simply integrates the
nanosecond converter that derives from device frequency and start time.
v2 -> v3:
- replace ib_verbs nanosecond converter with more generic method
based on device frequency and start time.

net/mlx5: query device frequency
ethdev: add API to query device frequency
pdump: convert timestamp to nanoseconds on Rx path

net/pcap: support hardware Tx timestamps
