# 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
