/* Tests in this file:
Basic RX/TX connect()/accept() Functionality:
[ ?] slam - perform thousands of the same call per second
[ ] random - act like a monkey, press all the buttons
[OK] simple client ipv4 - connect, send one message and wait for an echo
[OK] simple server ipv4 - accept, read one message and echo it back
[OK] simple client ipv6 - connect, send one message and wait for an echo
[OK] simple server ipv6 - accept, read one message and echo it back
[OK] sustained client ipv4 - connect and rx/tx many messages
[OK] sustained server ipv4 - accept and echo messages
[ ?] sustained client ipv6 - connect and rx/tx many messages
[ ?] sustained server ipv6 - accept and echo messages
[ ] comprehensive client ipv4 - test all ipv4/6 client simple/sustained modes
[ ] comprehensive server ipv6 - test all ipv4/6 server simple/sustained modes
Performance:
[ ] Throughput - Test maximum RX/TX speeds
[ ] Memory Usage - Test memory consumption profile
[ ] CPU Usage - Test processor usage
[ ] Multithreaded Throughput -
[ ] Multithreaded CPU Usage -
Correctness:
[ ] Block/Non-block - Test that blocking and non-blocking behaviour is consistent
[ ] Release of resources - Test that all destructor methods/blocks function properly
[ ] Multi-network handling - Test internal Tap multiplexing works for multiple networks
[ ] Address handling - Test that addresses are copied/parsed/returned properly
