Hi Arno,

some additional comments:


Jan,


I attached a zip file with some files. eth_trace1 is an ethereal capture
file.
By the way, when loading eepro100-rt.o it says 'Receiver lock-up woraround
activated', but I saw that this code is not active. After running a while I
can
see the message 'rteth0: can't fill rx buffer (force 0)!'. May it be
possible,
that all problems are caused by this damned chip and a receiver lock-up?

In the eepro100-rt, there are a lot of mechanisms deactivated which normally handle overload situations (or the rx-bug). This is feasible as the driver is intendend to run in a dedicated network with limited load (due to control mechanisms like RTmac/TDMA).


In the non RT environment I'm using the open source driver (e100.o) from
Intel without problems.


Our experience is that this driver is still not bug-free. Certain chip revisions of the 8255x do not work with the e100, while the "good old" eepro100 does.
