Subject: [dpdk-dev] [RFC PATCH 0/3] mlx5 to PCAP capture with hardware timestamps
Date: Thu, 25 Jun 2020 15:01:16 -0400
Message-ID: <20200625190119.265739-1-vivien.didelot@gmail.com> (raw)

This series allows to capture packets from a Mellanox ConnectX-5 interface
into a PCAP file with support for hardware timestamps. Since libibverbs
already provides timestamp conversion to nanoseconds for mlx5, the necessary
glue is added before writing the driver's timestamps into the PCAP headers.

Patrick Keroulas (2):
  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
