This is the patch to support NEC PC-9800 subarchitecture
against 2.5.64-ac4. (7/11)

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

+
+    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.  */
