  15     This driver should work with many programmed-I/O 8390-based ethernet
  16     boards.  Currently it supports the NE1000, NE2000, many clones,
  17     and some Cabletron products.

  19     Changelog:
  20 
  21     Paul Gortmaker      : use ENISR_RDC to monitor Tx PIO uploads, made
  22                           sanity checks and bad clone support optional.
  23     Paul Gortmaker      : new reset code, reset card after probe at boot.

  99 
 100    NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
 101    buffer memory space.  NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
 102    the SAPROM, while other supposed NE2000 clones must be detected by their
 103    SA prefix.
 104 
 105    Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
 106    mode results in doubled values, which can be detected and compensated for.
 107 
 108    The probe is also responsible for initializing the card and filling
 109    in the 'dev' and 'ei_status' structures.
 110 
 111    We use the minimum memory size for some ethercard product lines, iff we can't
 112    distinguish models.  You can increase the packet buffer size by setting
 113    PACKETBUF_MEMSIZE.  Reported Cabletron packet buffer locations are:
 114         E1010   starts at 0x100 and ends at 0x2000.
 115         E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")
 116         E2010    starts at 0x100 and ends at 0x4000.
 117         E2010-x starts at 0x100 and ends at 0xffff.  */
