- Linux driver for Racal-Interlan ES3210 EISA Network Adapter
-
- Copyright (C) 1996, Paul Gortmaker.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- Information and Code Sources:
-
- 1) The existing myriad of Linux 8390 drivers written by Donald Becker.
-
- 2) Once again Russ Nelson's asm packet driver provided additional info.
-
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
- Too bad it doesn't work -- see below.
-
- The ES3210 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- Which rules out using eth_io_copy_and_sum() in this driver.
-
- Apparently there are two slightly different revisions of the
- card, since there are two distinct EISA cfg files (!rii0101.cfg
- and !rii0102.cfg) One has media select in the cfg file and the
- other doesn't. Hopefully this will work with either.
-
- That is about all I can tell you about it, having never actually
- even seen one of these cards. :) Try http://www.interlan.com
- if you want more info.
-
- Thanks go to Mark Salazar for testing v0.02 of this driver.
-
- Bugs, to-fix, etc:
-
- 1) The EISA cfg ports that are *supposed* to have the IRQ and shared
- mem values just read 0xff all the time. Hrrmpf. Apparently the
- same happens with the packet driver as the code for reading
- these registers is disabled there. In the meantime, boot with:
- ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
- shared memory detection. (The i/o port detection is okay.)
-
- 2) Module support currently untested. Probably works though.

-
- Information and Code Sources:
-
- 1) Based upon framework of es3210 driver.
- 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
- 3) Russ Nelson's asm packet driver provided additional info.
- 4) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
-
- The LNE390 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- There are two versions of the card: the lne390a and the lne390b.
- Going by the EISA cfg files, the "a" has jumpers to select between
- BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
- The shared memory address selection is also slightly different.
- Note that shared memory address > 1MB are supported with this driver.
-
- You can try <http://www.mylex.com> if you want more info, as I've
- never even seen one of these cards. :)
-

- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
-
- The NE3210 is an EISA shared memory NS8390 implementation. Shared
- memory address > 1MB should work with this driver.
-
- Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched

-
- This driver WILL NOT WORK FOR THE NE3200 - it is completely different

-/* smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
-
-Sources:
-
- This driver is based on (cloned from) the ISA SMC Ultra driver
- written by Donald Becker. Modifications to support the EISA
- version of the card by Paul Gortmaker and Leonard N. Zubkoff.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
-Theory of Operation:
-
- The SMC Ultra32C card uses the SMC 83c790 chip which is also
- found on the ISA SMC Ultra cards. It has a shared memory mode of
- operation that makes it similar to the ISA version of the card.
- The main difference is that the EISA card has 32KB of RAM, but
- only an 8KB window into that memory. The EISA card also can be
- set for a bus-mastering mode of operation via the ECU, but that
- is not (and probably will never be) supported by this driver.
- The ECU should be run to enable shared memory and to disable the
- bus-mastering feature for use with linux.
-
- By programming the 8390 to use only 8KB RAM, the modifications
- to the ISA driver can be limited to the probe and initialization
- code. This allows easy integration of EISA support into the ISA
- driver. However, the driver development kit from SMC provided the
- register information for sliding the 8KB window, and hence the 8390
- is programmed to use the full 32KB RAM.
-
- Unfortunately this required code changes outside the probe/init
- routines, and thus we decided to separate the EISA driver from
- the ISA one. In this way, ISA users don't end up with a larger
- driver due to the EISA code, and EISA users don't end up with a
- larger driver due to the ISA EtherEZ PIO code. The driver is
- similar to the 3c503/16 driver, in that the window must be set
- back to the 1st 8KB of space for access to the two 8390 Tx slots.
-
- In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
- be a limiting factor, since the EISA bus could get packets off
- the card fast enough, but having the use of lots of RAM as Rx
- space is extra insurance if interrupt latencies become excessive.
