Subject: [dpdk-dev] [PATCH v2 0/6] net/pcap: build on Windows
Date: Sun, 14 Feb 2021 05:16:10 +0300	[thread overview]
Message-ID: <20210214021616.26970-1-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20210214012013.23165-1-dmitry.kozliuk@gmail.com>

Most modern and actively maintained distribution of libpcap for Windows is Npcap
(https://nmap.org/npcap). It is free (as in "free beer") and open-source, but
Npcap redistribution with commercial products may be limited by its license.

Npcap can be installed anywhere, so a new Meson option is provided to find it:

    meson -Dpcap_sdk=C:\Npcap -Dexamples=skeleton build

Example of collecting packets from an interface to a file:

    .\build\examples\dpdk-skeleton.exe `
        --vdev "eth_pcap0,iface=\Device\NPF_{DDD48985-A77C-4FC9-AF48-61E547C8797E}" `
        --vdev "eth_pcap1,tx_pcap=capture.pcap"

Implementation in "pcap_osdep_windows.c" does some guesswork to convert
between variants of an interface name. Microsoft experts and interested
users, please take a look and/or give it a try in your environment.

There are no release notes for 21.05 yet, will send update after they appear.

v2: fix microsecond calculation on Windows in patch 1/6.

Dmitry Kozlyuk (6):
  eal: add internal API for current time
  net/pcap: fix format string
  net/pcap: move OS-dependent code to separate files
  net/pcap: add libpcap wrappers
  config: discover libpcap on Windows
  net/pcap: build on Windows
