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.
-
- Upto 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 5539 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...

+
+ 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

+ 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, in linux/drivers/net/CONFIG, place e.g.

+
+ Yes, I know full duplex isn't permissible on BNC or AUI; they're just
