   2  * ni6510 (am7990 'lance' chip) driver for Linux-net-3
   3  * BETAcode v0.71 (96/09/29) for 2.0.0 (or later)
   4  * copyrights (c) 1994,1995,1996 by M.Hipp
   5  *
   6  * This driver can handle the old ni6510 board and the newer ni6510
   7  * EtherBlaster. (probably it also works with every full NE2100
   8  * compatible card)
   9  *
  10  * driver probes: io: 0x360,0x300,0x320,0x340 / dma: 3,5,6,7
  11  *
  12  * This is an extension to the Linux operating system, and is covered by the
  13  * same GNU General Public License that covers the Linux-kernel.

  15  * comments/bugs/suggestions can be sent to:
  16  *   Michael Hipp
  17  *   email: hippm@informatik.uni-tuebingen.de
  18  *
  19  * sources:
  20  *   some things are from the 'ni6510-packet-driver for dos by Russ Nelson'
  21  *   and from the original drivers by D.Becker
  22  *
  23  * known problems:
  24  *   - on some PCI boards (including my own) the card/board/ISA-bridge has
  25  *     problems with bus master DMA. This results in lotsa overruns.
  26  *     It may help to '#define RCV_PARANOIA_CHECK' or try to #undef
  27  *     the XMT and RCV_VIA_SKB option .. this reduces driver performance.
  28  *     Or just play with your BIOS options to optimize ISA-DMA access.
  29  *     Maybe you also wanna play with the LOW_PERFORAMCE and MID_PERFORMANCE
  30  *     defines -> please report me your experience then
  31  *   - Harald reported for ASUS SP3G mainboards, that you should use
  32  *     the 'optimal settings' from the user's manual on page 3-12!
  33  *
  34  * credits:
  35  *   thanx to Jason Sullivan for sending me a ni6510 card!
  36  *   lot of debug runs with ASUS SP3G Boards (Intel Saturn) by Harald Koenig

  38  * simple performance test: (486DX-33/Ni6510-EB receives from 486DX4-100/Ni6510-EB)
  39  *    average: FTP -> 8384421 bytes received in 8.5 seconds
  40  *           (no RCV_VIA_SKB,no XMT_VIA_SKB,PARANOIA_CHECK,4 XMIT BUFS, 8 RCV_BUFFS)
  41  *    peak: FTP -> 8384421 bytes received in 7.5 seconds
