Subject: [dpdk-dev] [PATCH v2 7/7] doc: update KNI documentation
Date: Mon, 10 Jun 2019 10:51:55 -0700	[thread overview]
Message-ID: <20190610175155.21374-8-stephen@networkplumber.org> (raw)
In-Reply-To: <20190610175155.21374-1-stephen@networkplumber.org>

Make the KNI documentation reflect modern kernel networking.
Ifconfig has been superseded by iproute2 for 15 years.
Iproute2 is well maintained, supports current feature set.

Ethtool is no longer supported by KNI.
Tshark is a better replacement for tcpdump.

 This is done by creating one or more kernel net devices for each of the DPDK ports.
