/*  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.  */
