[PATCH] Support PC-9800 subarchitecture (9/14) NIC 

This is the patch to support NEC PC-9800 subarchitecture
against 2.5.65-ac1. (9/14)

C-bus(PC98's legacy bus like ISA) network cards support.
Change IO port and IRQ assign.
Add NE2000 compatible driver for PC-9800.
  PCI netwwork card works fine without patch.

Regards,
Osamu Tomita

This driver should work with many programmed-I/O 8390-based ethernet
boards. Currently it supports the NE1000, NE2000, many clones,
and some Cabletron products.
Changelog:
Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
sanity checks and bad clone support optional.
Paul Gortmaker : new reset code, reset card after probe at boot.
Paul Gortmaker : multiple card support for module users.
Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
Paul Gortmaker : Allow users with bad cards to avoid full probe.
Paul Gortmaker : PCI probe changes, more PCI cards supported.
rjohnson@analogic.com : Changed init order so an interrupt will only
occur after memory is allocated for dev->priv. Deallocated memory
last in cleanup_modue()
Richard Guenther : Added support for ISAPnP cards
Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.
Osamu Tomita : Separate driver for NEC PC-9800.

/* Probe for various non-shared-memory ethercards.
NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
buffer memory space. NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
the SAPROM, while other supposed NE2000 clones must be detected by their
SA prefix.
Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
mode results in doubled values, which can be detected and compensated for.
The probe is also responsible for initializing the card and filling
in the 'dev' and 'ei_status' structures.
We use the minimum memory size for some ethercard product lines, iff we can't
distinguish models. You can increase the packet buffer size by setting
PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
E1010 starts at 0x100 and ends at 0x2000.
E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")
E2010 starts at 0x100 and ends at 0x4000.
E2010-x starts at 0x100 and ends at 0xffff. */
