So, is it better or worse than the Etherlink 3c501 ? :-D

IIRC it over-wrote the buffer the CPU tried to read with new packets from the network or something like that. I had it for a while in Linux and the performance really was bad. :-D

I remember the 3c590 (https://github.com/torvalds/linux/blob/20cb38a7af88dc40095da...) doing something awful too which required changing the PCI latency setting from 32 to 248 to avoid some catastrophic errors.

It's amazing how much stuff is hidden from view by drivers and firmware updates.

I've found the description of the thing: https://www.os2museum.com/wp/emulating-etherlink/

Mine is better because it has two buffers :) But still, only one received frame is kept.
