+
+    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.
+
+    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 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.

+
+    (C)Copyright 1997-1998 DAVICOM Semiconductor,Inc. All Rights Reserved.
+
+    Marcelo Tosatti <marcelo@conectiva.com.br> :
+    Made it compile in 2.3 (device to net_device)
+
+    Alan Cox <alan@redhat.com> :
+    Cleaned up for kernel merge.
+    Removed the back compatibility support
+    Reformatted, fixing spelling etc as I went
+    Removed IRQ 0-15 assumption
+
+    Jeff Garzik <jgarzik@pobox.com> :
+    Updated to use new PCI driver API.
+    Resource usage cleanups.
+    Report driver version to user.
+
+    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.
+
+    Alan Cox <alan@redhat.com>
+    Added new PCI identifiers provided by Clear Zhang at ALi 
+    for their 1563 ethernet device.
+
+    TODO
+
+    Implement pci_driver::suspend() and pci_driver::resume()
+    power management methods.
+
+    Check on 64 bit boxes.
+    Check and fix on big endian boxes.
+
+    Test and make sure PCI latency is now correct for all cases.

+/*
+				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.

+/*
+				Theory of Operation
+
+I. Board Compatibility
+
+This device driver was forked from the driver for the DECchip "Tulip",
+Digital's single-chip ethernet controllers for PCI.  It supports Xircom's
+almost-Tulip-compatible CBE-100 CardBus adapters.
+
+II. Board-specific settings
+
+PCI bus devices are configured by the system at boot time, so no jumpers
+need to be set on the board.  The system BIOS preferably should assign the
+PCI INTA signal to an otherwise unused system IRQ line.
+
+III. Driver operation
+
+IIIa. Ring buffers
+
+The Xircom can use either ring buffers or lists of Tx and Rx descriptors.
+This driver uses statically allocated rings of Rx and Tx descriptors, set at
+compile time by RX/TX_RING_SIZE.  This version of the driver allocates skbuffs
+for the Rx ring buffers at open() time and passes the skb->data field to the
+Xircom as receive data buffers.  When an incoming frame is less than
+RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is
+copied to the new skbuff.  When the incoming frame is larger, the skbuff is
+passed directly up the protocol stack and replaced by a newly allocated
+skbuff.
+
+The RX_COPYBREAK value is chosen to trade-off the memory wasted by
+using a full-sized skbuff for small frames vs. the copying costs of larger
+frames.  For small frames the copying cost is negligible (esp. considering
+that we are pre-loading the cache with immediately useful header
+information).  For large frames the copying cost is non-trivial, and the
+larger copy might flush the cache of useful data.  A subtle aspect of this
+choice is that the Xircom only receives into longword aligned buffers, thus
+the IP header at offset 14 isn't longword aligned for further processing.
+Copied frames are put into the new skbuff at an offset of "+2", thus copying
+has the beneficial effect of aligning the IP header and preloading the
+cache.
+
+IIIC. Synchronization
+The driver runs as two independent, single-threaded flows of control.  One
+is the send-packet routine, which enforces single-threaded use by the
+dev->tbusy flag.  The other thread is the interrupt handler, which is single
+threaded by the hardware and other software.
+
+The send packet thread has partial control over the Tx ring and 'dev->tbusy'
+flag.  It sets the tbusy flag whenever it's queuing a Tx packet. If the next
+queue slot is empty, it clears the tbusy flag when finished otherwise it sets
+the 'tp->tx_full' flag.
+
+The interrupt handler has exclusive control over the Rx ring and records stats
+from the Tx ring.  (The Tx-done interrupt can't be selectively turned off, so
+we can't avoid the interrupt overhead by having the Tx routine reap the Tx
+stats.)	 After reaping the stats, it marks the queue entry as empty by setting
+the 'base' to zero.	 Iff the 'tp->tx_full' flag is set, it clears both the
+tx_full and tbusy flags.
