i just test it on Linux localhost.localdomain 2.6.31.5-127.fc12.x86_64 #1 SMP Sat Nov 7 21:11:14 EST 2009 x86_64 x86_64 x86_64 GNU/Linux.
with hardware, Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (rev b0)
device id : 1969:1026 (rev b0)

i upload/download a 382M it work well with retransmit packet:

Tcp: RtoAlgorithm RtoMin RtoMax MaxConn ActiveOpens PassiveOpens AttemptFails EstabResets CurrEstab InSegs OutSegs RetransSegs InErrs OutRsts
Tcp: 1 200 120000 -1 2 4 2 0 2 532501 220631 6 0 2
