+				Theory of Operation
+
+I. Board Compatibility
+
+This device driver is designed for the 3Com FastEtherLink and FastEtherLink
+XL, 3Com's PCI to 10/100baseT adapters.  It also works with the 10Mbs
+versions of the FastEtherLink cards.  The supported product IDs are
+  3c590, 3c592, 3c595, 3c597, 3c900, 3c905
+
+The related ISA 3c515 is supported with a separate driver, 3c515.c, included
+with the kernel source or available from
+    cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
+
+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 should be set to assign the
+PCI INTA signal to an otherwise unused system IRQ line.
+
+The EEPROM settings for media type and forced-full-duplex are observed.
+The EEPROM media type should be left at the default "autoselect" unless using
+10base2 or AUI connections which cannot be reliably detected.
+
+III. Driver operation
+
+The 3c59x series use an interface that's very similar to the previous 3c5x9
+series.  The primary interface is two programmed-I/O FIFOs, with an
+alternate single-contiguous-region bus-master transfer (see next).
+
+The 3c900 "Boomerang" series uses a full-bus-master interface with separate
+lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
+DEC Tulip and Intel Speedo3.  The first chip version retains a compatible
+programmed-I/O interface that has been removed in 'B' and subsequent board
+revisions.
+
+One extension that is advertised in a very large font is that the adapters
+are capable of being bus masters.  On the Vortex chip this capability was
+only for a single contiguous region making it far less useful than the full
+bus master capability.  There is a significant performance impact of taking
+an extra interrupt or polling for the completion of each transfer, as well
+as difficulty sharing the single transfer engine between the transmit and
+receive threads.  Using DMA transfers is a win only with large blocks or
+with the flawed versions of the Intel Orion motherboard PCI controller.
+
+The Boomerang chip's full-bus-master interface is useful, and has the
+currently-unused advantages over other similar chips that queued transmit
+packets may be reordered and receive buffer groups are associated with a
+single frame.
+
+With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
+Rather than a fixed intermediate receive buffer, this scheme allocates
+full-sized skbuffs as receive buffers.  The value RX_COPYBREAK is used as
+the copying breakpoint: it is chosen to trade-off the memory wasted by
+passing the full-sized skbuff to the queue layer for all frames vs. the
+copying cost of copying a frame to a correctly-sized skbuff.
+
+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.
+
+IV. Notes
+
+Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
+3c590, 3c595, and 3c900 boards.
+The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
+the EISA version is called "Demon".  According to Terry these names come
+from rides at the local amusement park.
+
+The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
+This driver only supports ethernet packets because of the skbuff allocation
+limit of 4K.
