So, is it better or worse than the Etherlink 3c501 ? :-D https://mirror.math.princeton.edu/pub/oldlinux/Linux.old/net/tcpip/ne2000/3c501.c https://mirror.math.

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
- tech2 3y agoI remember the 3c590 (https://github.com/torvalds/linux/blob/20cb38a7af88dc40095da7c2c9094da3873fea23/drivers/net/ethernet/3com/3c59x.c#L1187 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.
- ynoxinul 3y agoI've found the description of the thing: https://www.os2museum.com/wp/emulating-etherlink/ https://www.os2museum.com/wp/emulating-etherlink/ Mine is better because it has two buffers :) But still, only one received frame is kept.
