# Tests that a separate network namespace can configure and communicate
# over the devices it sees. Tests are done using netlink(7) ('ip' command)
# or ioctl(2) ('ifconfig' command) for controlling devices.
#
# There are three test cases:
# 1,2. communication over paired veth (virtual ethernet) devices
#      from two different network namespaces (each namespace has
#      one device)
#   3. communication over the lo (localhost) device in a separate
#      network namespace
