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. To set some context, the 3c501 was designed in the 1980's to be used on 8088 PC-XT 8bit ISA machines. It was built using a large number of discrete TTL components and truly looks like a relic of the ancient past before large scale integration was common. 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.

* INET An implementation of the TCP/IP protocol suite for the LINUX

* interface as the means of communication with the user level.
|
|
*
|
|
* Holds initial configuration information for devices.

|
* Authors: Ross Biro

* Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
|

* Donald J. Becker, <becker@scyld.com>
|
|
*
|
|
* Changelog:
|
|
* Stephen Hemminger (09/2003)
|
|
* - get rid of pre-linked dev list, dynamic device allocation
|
|
* Paul Gortmaker (03/2002)
|
|
* - struct init cleanup, enable multiple ISA autoprobes.
|
|
* Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
|
|
* - fix sbni: s/device/net_device/
|
|
* Paul Gortmaker (06/98):
|
|
* - sort probes in a sane way, make sure all (safe) probes
|
|
* get run once & failed autoprobes don't autoprobe again.
