drivers/net: delete the really obsolete 8390 based 10Mbit ISA drivers
This is an area I know all too well, after being author of several 8390
drivers, and maintainer of all 8390 drivers during a large part of their
active lifecycle.
To that end, I can say this with a reasonable degree of confidence.
The drivers deleted here represent the earliest (as in early 1990)
hardware and/or rare hardware. The remaining hardware not deleted
here is the more modern/sane of the lot, with ISA-PnP and jumperless
"soft configuration" like the wd and smc cards had.
The original ne2000 driver (ne.c) gets a pass at this time since
AT/LANTIC based cards that could be both ne2000 or wd-like (with
shared memory) and with jumperless configuration were made in the
mid to late 1990's, and performed reasonably well for their era.

Either someone wasn't - too used to dem bit en bites, or they were trying to obfuscate the - programming interface. - - There is an additional complication when setting the window on the packet - buffer. You must first do a read into the packet buffer region with the - low 8 address bits the address setting the page for the start of the packet - buffer window, and then do the above operation. See mem_on() for details. - - One bug on the chip is that even a hard reset won't disable the memory - window, usually resulting in a hung machine if mem_off() isn't called. - If this happens, you must power down the machine for about 30 seconds. -*/ - < |
