It provides the following functions:
* basic setup and cleanup
* making TCP background traffic
* checking connectivity between test hosts
Moreover it defines new IPV4_NET16_UNUSED and IPV6_NET32_UNUSED
variables. They are needed because some of the interface tests
add more then 254 new addresses to interface which could overlap
with existed ones on test network.
