net/udpgso_bench.sh add UDP GSO audit tests
Audit tests count the total number of messages sent and compares
with total number of CMSG received on error queue. Example:
udp gso zerocopy timestamp audit
udp rx: 1599 MB/s 1166414 calls/s
udp tx: 1615 MB/s 27395 calls/s 27395 msg/s
udp rx: 1634 MB/s 1192261 calls/s
udp tx: 1633 MB/s 27699 calls/s 27699 msg/s
udp rx: 1633 MB/s 1191358 calls/s
udp tx: 1631 MB/s 27678 calls/s 27678 msg/s
Summary over 4.000 seconds...
sum udp tx: 1665 MB/s 82772 calls (27590/s) 82772 msgs (27590/s)
Tx Timestamps: 82772 received 0 errors
Zerocopy acks: 82772 received
Errors are thrown if CMSG count does not equal send count,
example:
Summary over 4.000 seconds...
sum tcp tx: 7451 MB/s 493706 calls (123426/s) 493706 msgs (123426/s)
./udpgso_bench_tx: Unexpected number of Zerocopy completions: 493706 expected 493704 received
Also reduce individual test time from 4 to 3 seconds so that
overall test time does not increase significantly.
v3: Enhancements as per Willem de Bruijn <willemb@google.com>
- document -P option for TCP audit
