drivers/net: delete the really obsolete 8390 based 10Mbit ISA drivers

Browse Source 
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.

This driver should work with the 3c503 and 3c503/16. It should be used
in shared memory mode for best performance, although it may also work
in programmed-I/O mode.

Changelog:
Paul Gortmaker : add support for the 2nd 8kB of RAM on 16 bit cards.
Paul Gortmaker : multiple card support for module users.
rjohnson@analogic.com : Fix up PIO interface for efficient operation.
Jeff Garzik : ethtool support

The E2100 series ethercard is a fairly generic shared memory 8390
implementation. The only unusual aspect is the way the shared memory
registers are set: first you do an inb() in what is normally the
station address region, and the low three bits of next outb() *address*
is used as the write value for that register. 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.

/*
The HP EtherTwist chip implementation is a fairly routine DP8390
implementation. It allows both shared memory and programmed-I/O buffer
access, using a custom interface for both. The programmed-I/O mode is
entirely implemented in the HP EtherTwist chip, bypassing the problem
ridden built-in 8390 facilities used on NE2000 designs. The shared
memory mode is likewise special, with an offset register used to make
packets appear at the shared memory base. Both modes use a base and bounds
page register to hide the Rx ring buffer wrap -- a packet that spans the
end of physical buffer memory appears continuous to the driver. (c.f. the
3c503 and Cabletron E2100)
A special note: the internal buffer of the board is only 8 bits wide.
This lays several nasty traps for the unaware:
- the 8390 must be programmed for byte-wide operations
- all I/O and memory operations must work on whole words (the access
latches are serially preloaded and have no byte-swapping ability).
This board is laid out in I/O space much like the earlier HP boards:
the first 16 locations are for the board registers, and the second 16 are
for the 8390. The board is easy to identify, with both a dedicated 16 bit
ID register and a constant 0x530* value in the upper bits of the paging
register.
