The COPS Appletalk support is very old, never said to actually work properly, and the firmware code for the devices are under a very suspect license. Remove it all to clear up the license issue, if it is still needed and actually used by anyone, we can add it back later once the license is cleared up.

|
|
* 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.
