[microblaze-uclinux] 91c111 tcp/ip

[Matthias Heise <m.heise@xxxxxxxxx>]

good morning,

I can observe different behaviour between  Internet Explorer and Firefox 
. When I try to connect with Internet Explorer the message "tcp: 
incorrect acknum" is thrown out and in ethereal I can see a http-packet 
with an incorrect tcp checksum, the system stays in a loop of obviously 
wrong transmissions and continues to throw the acknum error. With 
Firefox there is the above described RST loop and no http transmissions 
at all.
Why should the tcp checksum be calculated  incorrect when it works with 
the other TCP frames that are transmittet before ? By the way (to 
Georges question) I'm not working with linux but with a "bare" 
microblaze and a ping to the system is possible but there are two of 
four transmissions lost. Has anyone a deeper knowledge of all this and 
can help me ? Thank you for your time and patience.
