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.

eal: add internal API for current time
net/pcap: fix format string
net/pcap: move OS-dependent code to separate files
