It was amusing that linux was able to make use of this 1980's technology on machines long past its intended lifespan, but it probably should go now -- it is causing issues in some distros[1], and while that might be fixable, it is just not worth it. To set the context, the 3c501 was designed in the 1980's to be used on 8088 PC-XT 8bit ISA machines. It was built using discrete TTL components and truly looks like a relic of the past. But from a functional point of view, the real issue, as stated in the (also obsolete) Ethernet-HowTo, is that "...the 3c501 can only do one thing at a time -- while you are removing one packet from the single-packet buffer it cannot receive another packet, nor can it receive a packet while loading a transmit packet." You know things are not good when the Kconfig help text suggests you make a cron job doing a ping every minute. Hardware that old and crippled is simply not going to be used by anyone in a time where 10 year old 100Mbit PCI cards (that are still functional) are largely give-away items.

Alan, any objections?
