- * net-3-driver for the NI5210 card (i82586 Ethernet chip)
- *
- * This is an extension to the Linux operating system, and is covered by the
- * same GNU General Public License that covers that work.
- *
- * Alphacode 0.82 (96/09/29) for Linux 2.0.0 (or later)
- * Copyrights (c) 1994,1995,1996 by M.Hipp (hippm@informatik.uni-tuebingen.de)
- * [feel free to mail ....]
- *
- * when using as module: (no autoprobing!)
- * run with e.g:
- * insmod ni52.o io=0x360 irq=9 memstart=0xd0000 memend=0xd4000
- *
- * CAN YOU PLEASE REPORT ME YOUR PERFORMANCE EXPERIENCES !!.
- *
- * If you find a bug, please report me:
- * The kernel panic output and any kmsg from the ni52 driver
- * the ni5210-driver-version and the linux-kernel version
- * how many shared memory (memsize) on the netcard,
- * bootprom: yes/no, base_addr, mem_start
- * maybe the ni5210-card revision and the i82586 version
- *
- * autoprobe for: base_addr: 0x300,0x280,0x360,0x320,0x340
- * mem_start: 0xd0000,0xd2000,0xc8000,0xca000,0xd4000,0xd6000,
- * 0xd8000,0xcc000,0xce000,0xda000,0xdc000
- *
- * sources:
- * skeleton.c from Donald Becker
- *
- * I have also done a look in the following sources: (mail me if you need them)
- * crynwr-packet-driver by Russ Nelson
- * Garret A. Wollman's (fourth) i82586-driver for BSD
- * (before getting an i82596 (yes 596 not 586) manual, the existing drivers
- * helped me a lot to understand this tricky chip.)
- *
- * Known Problems:
- * The internal sysbus seems to be slow. So we often lose packets because of
- * overruns while receiving from a fast remote host.
- * This can slow down TCP connections. Maybe the newer ni5210 cards are
- * better. My experience is, that if a machine sends with more than about
- * 500-600K/s the fifo/sysbus overflows.
- *
- * IMPORTANT NOTE:
- * On fast networks, it's a (very) good idea to have 16K shared memory. With
- * 8K, we can store only 4 receive frames, so it can (easily) happen that a
- * remote machine 'overruns' our system.
- *
- * Known i82586/card problems (I'm sure, there are many more!):
- * Running the NOP-mode, the i82586 sometimes seems to forget to report
- * every xmit-interrupt until we restart the CU.
- * Another MAJOR bug is, that the RU sometimes seems to ignore the EL-Bit
- * in the RBD-Struct which indicates an end of the RBD queue.
- * Instead, the RU fetches another (randomly selected and
- * usually used) RBD and begins to fill it. (Maybe, this happens only if
- * the last buffer from the previous RFD fits exact into the queue and
- * the next RFD can't fetch an initial RBD. Anyone knows more? )
- *
- * results from ftp performance tests with Linux 1.2.5
- * send and receive about 350-400 KByte/s (peak up to 460 kbytes/s)
- * sending in NOP-mode: peak performance up to 530K/s (but better don't
- * run this mode)
