Question Ping works but TCP sessions fail on custom Ethernet driver


Hi everyone,

I am _STILL_ working on a custom ethernet driver. I have finally got "ping" working but when I run Boa and try to connect to uClinux using another computer on the network it does not work.
I see the following packets in wireshark:

from my computer to uClinux:
Quote:
42728 > http [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=11783704 TSER=0 WS=6
from uClinux to my computer:
Quote:
http > 42728 [RST, ACK] Seq=1 Win=0 Len=0
I have the same problem when trying to start a Telnet session. When I run the same configuration using the DM9000 driver Boa works fine.

Does any one have any idea where my problem might be? Do I need to adjust some parameters in the uClinux TCP/IP stack configuration? My driver passes the skb up using netif_rx just like in the DM9000.

Thank you for any input,
Austin.
