Thanks.
I'll try my best, but I am running out of time, and it is still not as it
should. I still have trouble identifying the right place where receive buffer
descriptors should be cache-invalidated. At one point, a magic
flush_dcache_all() at a certain place in code made it work, but that can't be
entirely correct, and if I replace it with only the necessary ranges, it
doesn't work correctly anymore, so I guess this flush is also invalidating
something I need elsewhere :-(
I keep searching.... through the IMO fairly convoluted network code.
Best regards,
