Not that I'm arguing to keep ed(4), I have three ne2000 PCI cards in my des= k here. Sure one could insert one in a current machine, but why? --- Sent using a tiny phone keyboard. Apologies for any typos and autocorrect. Also, this old phone only supports top post. Apologies.

Even 1000 different cards or 10,000. The ed(4) driver likely supported in excess of 1000 different cards because so many people made ne-2000 compatible cards... in the early 1990s. However, since nobody has ISA or PC Card (not CardBus) interfaces anymore (those machines topped out around 32-64MB, which FreeBSD no longer works well on), the benefit to the project is quite low. Even the 'newer' PC Card versions that were 10/100 couldn't get more than about 10-12Mbps due to ISA/PC Card bus speed limitations. The PCI versions were never popular (I had to hunt a bunch for them 10 years ago when I was finishing up my activities on the driver for my vast PC Card collection to find an example to test), and even it had trouble beyond 20Mbps because it wasn't DMA'd. The ED driver was a solid driver last time I tried it, but when I can plug in dozens of 100Mbps or 1Gbps cards into the same CardBus slot and those cost < $10 now, there's very little return on programmer time to keeping this one going. However, having said all that, if we can document 5 real users of this card on machines running FreeBSD 12, it will meet the criteria for remaining, just like any other driver.... So far we've found 0, while we have found many other users of other drivers.
