Subject: [patch v2, iproute2 version 3.2.0] Source mode for macvlan
interface
From: Stefan Gula <steweg@...il.com>
Adjusting iproute2 utility to support new macvlan link type mode
called "source". Example of commands that can be applied:
ip link add link eth0 name macvlan0 type macvlan mode source
ip link set link macvlan0 type macvlan macaddr add 00:11:11:11:11:11
ip link set link macvlan0 type macvlan macaddr del 00:11:11:11:11:11
ip link set link macvlan0 type macvlan macaddr flush
Signed-off-by: Stefan Gula <steweg@...il.com>
