The intention is to produce a pcap with nanosecond precision when 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 is already implemented by ibverbs. The conversion is performed is pdump rx callback.
