Linux Accurate ECN test sets using ACE counters and AccECN options to
cover several scenarios: Connection teardown, different ACK conditions,
counter wrapping, SACK space grabbing, fallback schemes, negotiation
retransmission/reorder/loss, AccECN option drop/loss, different
handshake reflectors, data with marking, and different sysctl values.
