# SYNOPSIS:
# netns_breakns.sh <NS_EXEC_PROGRAM> <IP_VERSION> <COMM_TYPE>
#
# OPTIONS:
#	* NS_EXEC_PROGRAM (ns_exec|ip)
#		Program which will be used to enter and run other commands
#		inside a network namespace.
#	* IP_VERSION (ipv4|ipv6)
#		Version of IP. (ipv4|ipv6)
#	* COMM_TYPE (netlink|ioctl)
#		Communication type between kernel and user space
#		for basic setup: enabling and assigning IP addresses
#		to the virtual ethernet devices. (Uses 'ip' command for netlink
#		and 'ifconfig' for ioctl.)
#
# Tests communication with ip (uses netlink) and ifconfig (uses ioctl)
# over a device which is not visible from the current network namespace.
#
# There are two test cases which are trying to set an ip address on the veth1
# device which is not inside the network namespace referred to by NS_HANDLE0:
# 1. using netlink (ip command).
# 2. using ioctl (ifconfig command).
