ewrk3/tulip: Move the DEC - Tulip drivers
Move the DEC - Tulip driver into drivers/net/ethernet/dec/tulip/ and make the necessary Kconfig and Makefile changes. The Digital Equioment (DEC) driver ewrk3 was moved into drivers/net/ethernet/dec/ and the remaining drivers (Tulip) were moved into drivers/net/ethernet/dec/tulip/ CC: Tobias Ringstrom <tori@unhappy.mine.nu> CC: Grant Grundler <grundler@parisc-linux.org> CC: David Davies <davies@maniac.ultranet.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Acked-by: Grant Grundler <grundler@parisc-linux.org>

-
- Originally, this driver was written for the Digital Equipment
- Corporation series of EtherWORKS ethernet cards:
-
- DE425 TP/COAX EISA
- DE434 TP PCI
- DE435 TP/COAX/AUI PCI
- DE450 TP/COAX/AUI PCI
- DE500 10/100 PCI Fasternet
-
- but it will now attempt to support all cards which conform to the
- Digital Semiconductor SROM Specification. The driver currently
- recognises the following chips:
-
- DC21040 (no SROM)
- DC21041[A]
- DC21140[A]
- DC21142
- DC21143
-
- So far the driver is known to work with the following cards:
-
- KINGSTON
- Linksys
- ZNYX342
- SMC8432
- SMC9332 (w/new SROM)
- ZNYX31[45]
- ZNYX346 10/100 4 port (can act as a 10/100 bridge!)
-
- The driver has been tested on a relatively busy network using the DE425,
- DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred
- 16M of data to a DECstation 5000/200 as follows:
-
- TCP UDP
- TX RX TX RX
- DE425 1030k 997k 1170k 1128k
- DE434 1063k 995k 1170k 1125k
- DE435 1063k 995k 1170k 1125k
- DE500 1063k 998k 1170k 1125k in 10Mb/s mode
-
- All values are typical (in kBytes/sec) from a sample of 4 for each
- measurement. Their error is +/-20k on a quiet (private) network and also
- depend on what load the CPU has.
-
- =========================================================================
- This driver has been written substantially from scratch, although its
- inheritance of style and stack interface from 'ewrk3.c' and in turn from
- Donald Becker's 'lance.c' should be obvious. With the module autoload of
- every usable DECchip board, I pinched Donald's 'next_module' field to
- link my modules together.
-
- Up to 15 EISA cards can be supported under this driver, limited primarily
- by the available IRQ lines. I have checked different configurations of
- multiple depca, EtherWORKS 3 cards and de4x5 cards and have not found a
- problem yet (provided you have at least depca.c v0.38) ...
-
- PCI support has been added to allow the driver to work with the DE434,
- DE435, DE450 and DE500 cards. The I/O accesses are a bit of a kludge due
- to the differences in the EISA and PCI CSR address offsets from the base
- address.
-
- The ability to load this driver as a loadable module has been included
- and used extensively during the driver development (to save those long
- reboot sequences). Loadable module support under PCI and EISA has been
- achieved by letting the driver autoprobe as if it were compiled into the
- kernel. Do make sure you're not sharing interrupts with anything that
- cannot accommodate interrupt sharing!
-
- To utilise this ability, you have to do 8 things:
-
- 0) have a copy of the loadable modules code installed on your system.
- 1) copy de4x5.c from the /linux/drivers/net directory to your favourite
- temporary directory.
- 2) for fixed autoprobes (not recommended), edit the source code near
- line 5594 to reflect the I/O address you're using, or assign these when
- loading by:
-
- insmod de4x5 io=0xghh where g = bus number
- hh = device number
-
- NB: autoprobing for modules is now supported by default. You may just
- use:
-
- insmod de4x5
-
- to load all available boards. For a specific board, still use
- the 'io=?' above.
- 3) compile de4x5.c, but include -DMODULE in the command line to ensure
- that the correct bits are compiled (see end of source code).
- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
- kernel with the de4x5 configuration turned off and reboot.
- 5) insmod de4x5 [io=0xghh]
- 6) run the net startup bits for your new eth?? interface(s) manually
- (usually /etc/rc.inet[12] at boot time).
- 7) enjoy!
-
- To unload a module, turn off the associated interface(s)
- 'ifconfig eth?? down' then 'rmmod de4x5'.
-
- Automedia detection is included so that in principal you can disconnect
- from, e.g. TP, reconnect to BNC and things will still work (after a
- pause whilst the driver figures out where its media went). My tests
- using ping showed that it appears to work....
-
- By default, the driver will now autodetect any DECchip based card.
- Should you have a need to restrict the driver to DIGITAL only cards, you
- can compile with a DEC_ONLY define, or if loading as a module, use the
- 'dec_only=1' parameter.
-
- I've changed the timing routines to use the kernel timer and scheduling
- functions so that the hangs and other assorted problems that occurred
- while autosensing the media should be gone. A bonus for the DC21040
- auto media sense algorithm is that it can now use one that is more in
- line with the rest (the DC21040 chip doesn't have a hardware timer).
- The downside is the 1 'jiffies' (10ms) resolution.
-
- IEEE 802.3u MII interface code has been added in anticipation that some
- products may use it in the future.
-
- The SMC9332 card has a non-compliant SROM which needs fixing - I have
- patched this driver to detect it because the SROM format used complies
- to a previous DEC-STD format.
-
- I have removed the buffer copies needed for receive on Intels. I cannot
- remove them for Alphas since the Tulip hardware only does longword
- aligned DMA transfers and the Alphas get alignment traps with non
- longword aligned data copies (which makes them really slow). No comment.
-
- I have added SROM decoding routines to make this driver work with any
- card that supports the Digital Semiconductor SROM spec. This will help
- all cards running the dc2114x series chips in particular. Cards using
- the dc2104x chips should run correctly with the basic driver. I'm in
- debt to <mjacob@feral.com> for the testing and feedback that helped get
- this feature working. So far we have tested KINGSTON, SMC8432, SMC9332
- (with the latest SROM complying with the SROM spec V3: their first was
- broken), ZNYX342 and LinkSys. ZYNX314 (dual 21041 MAC) and ZNYX 315
- (quad 21041 MAC) cards also appear to work despite their incorrectly
- wired IRQs.
-
- I have added a temporary fix for interrupt problems when some SCSI cards
- share the same interrupt as the DECchip based cards. The problem occurs
- because the SCSI card wants to grab the interrupt as a fast interrupt
- (runs the service routine with interrupts turned off) vs. this card
- which really needs to run the service routine with interrupts turned on.
- This driver will now add the interrupt service routine as a fast
- interrupt if it is bounced from the slow interrupt. THIS IS NOT A
- RECOMMENDED WAY TO RUN THE DRIVER and has been done for a limited time
- until people sort out their compatibility issues and the kernel
- interrupt service code is fixed. YOU SHOULD SEPARATE OUT THE FAST
- INTERRUPT CARDS FROM THE SLOW INTERRUPT CARDS to ensure that they do not
- run on the same interrupt. PCMCIA/CardBus is another can of worms...
-
- Finally, I think I have really fixed the module loading problem with
- more than one DECchip based card. As a side effect, I don't mess with
- the device structure any more which means that if more than 1 card in
- 2.0.x is installed (4 in 2.1.x), the user will have to edit
- linux/drivers/net/Space.c to make room for them. Hence, module loading
- is the preferred way to use this driver, since it doesn't have this
- limitation.
-
- Where SROM media detection is used and full duplex is specified in the
- SROM, the feature is ignored unless lp->params.fdx is set at compile
- time OR during a module load (insmod de4x5 args='eth??:fdx' [see
- below]). This is because there is no way to automatically detect full
- duplex links except through autonegotiation. When I include the
- autonegotiation feature in the SROM autoconf code, this detection will
- occur automatically for that case.
-
- Command line arguments are now allowed, similar to passing arguments
- through LILO. This will allow a per adapter board set up of full duplex
- and media. The only lexical constraints are: the board name (dev->name)
- appears in the list before its parameters. The list of parameters ends
- either at the end of the parameter list or with another board name. The
- following parameters are allowed:
-
- fdx for full duplex
- autosense to set the media/speed; with the following
- sub-parameters:
- TP, TP_NW, BNC, AUI, BNC_AUI, 100Mb, 10Mb, AUTO
-
- Case sensitivity is important for the sub-parameters. They *must* be
- upper case. Examples:
-
- insmod de4x5 args='eth1:fdx autosense=BNC eth0:autosense=100Mb'.
-
- For a compiled in driver, at or above line 548, place e.g.
- #define DE4X5_PARM "eth0:fdx autosense=AUI eth2:autosense=TP"
-
- Yes, I know full duplex isn't permissible on BNC or AUI; they're just
- examples. By default, full duplex is turned off and AUTO is the default
- autosense setting. In reality, I expect only the full duplex option to
- be used. Note the use of single quotes in the two examples above and the
- lack of commas to separate items. ALSO, you must get the requested media
- correct in relation to what the adapter SROM says it has. There's no way
- to determine this in advance other than by trial and error and common
- sense, e.g. call a BNC connectored port 'BNC', not '10Mb'.
-
- Changed the bus probing. EISA used to be done first, followed by PCI.
- Most people probably don't even know what a de425 is today and the EISA
- probe has messed up some SCSI cards in the past, so now PCI is always
- probed first followed by EISA if a) the architecture allows EISA and
- either b) there have been no PCI cards detected or c) an EISA probe is
- forced by the user. To force a probe include "force_eisa" in your
- insmod "args" line; for built-in kernels either change the driver to do
- this automatically or include #define DE4X5_FORCE_EISA on or before
- line 1040 in the driver.

-
- Tobias Ringstrom <tori@unhappy.mine.nu> :
- Cleaned up and added SMP safety. Thanks go to Jeff Garzik,
- Andrew Morton and Frank Davis for the SMP safety fixes.
-
- Vojtech Pavlik <vojtech@suse.cz> :
- Cleaned up pointer arithmetics.
- Fixed a lot of 64bit issues.
- Cleaned up printk()s a bit.
- Fixed some obvious big endian problems.
-
- Tobias Ringstrom <tori@unhappy.mine.nu> :
- Use time_after for jiffies calculation. Added ethtool
- support. Updated PCI resource allocation. Do not
- forget to unmap PCI mapped skbs.

-/*
- Theory of Operation
-
-I. Board Compatibility
-
-This driver is for the Winbond w89c840 chip.
-
-II. Board-specific settings
-
-None.
-
-III. Driver operation
-
-This chip is very similar to the Digital 21*4* "Tulip" family. The first
-twelve registers and the descriptor format are nearly identical. Read a
-Tulip manual for operational details.
-
-A significant difference is that the multicast filter and station address are
-stored in registers rather than loaded through a pseudo-transmit packet.
-
-Unlike the Tulip, transmit buffers are limited to 1KB. To transmit a
-full-sized packet we must use both data buffers in a descriptor. Thus the
-driver uses ring mode where descriptors are implicitly sequential in memory,
-rather than using the second descriptor address as a chain pointer to
-subsequent descriptors.
-
-IV. Notes
-
-If you are going to almost clone a Tulip, why not go all the way and avoid
-the need for a new driver?
-
-IVb. References
-
-http://www.scyld.com/expert/100mbps.html
-http://www.scyld.com/expert/NWay.html
-http://www.winbond.com.tw/
-
-IVc. Errata
-
-A horrible bug exists in the transmit FIFO. Apparently the chip doesn't
-correctly detect a full FIFO, and queuing more than 2048 bytes may result in
-silent data corruption.
-
-Test with 'ping -s 10000' on a fast computer.
