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. The packetdrill used is commit cbe405666c9c8698ac1e72f5e8ffc551216dfa56 of repo: https://github.com/minuscat/packetdrill/tree/upstream_accecn. And corresponding patches are sent to google/packetdrill email list.
