DUP ACK 's seen in the packet capture, while doing throughput testing or file transfers
Issue
During throughput testing, large file transfers or any kind of steady data transfers, using tcp as transport, a packet capture will show, when parsed with a capture analyzer (like wireshark), "duplicate ack" packets.
The throughput and the general results of the tests are as expected (everything appears to work fine).
Environment
RHEL, any version, using tcp/ip, on an ethernet-type network (copper, fiber, or wireless/802.11)
