[ECOS] Pb with socket: TCP previous segment lost

[Nicolas Brouard <nicolas dot brouard at silicomp dot ca>]

Hi,
I have a board based on a MPC860 with FreeBSD stack. When I create a TCP 
socket and transfer a big buffer from my board to my PC, I have a lot a 
"TCP previous segment lost". One second after the lost frame, the 
retransmission occurs. So the transfert rate is like 0.01 Mbits/s !!!
With UDP (TFTP transfert), everything seems to work fine.

The same problem appears with OpenBSD stack.
Do I miss something in my stack configuration ?
Does anybody have the same problem ?
Thank's for your help

I attach the ethereal trace and the configuration file.
PC: 192.168.1.109,
board: 192.168.1.169
