- * Winbond fast ethernet PCI NIC driver
- *
- * Supports various cheap network adapters based on the Winbond W89C840F
- * fast ethernet controller chip. This includes adapters manufactured by
- * Winbond itself and some made by Linksys.

- */
-/*
- * The Winbond W89C840F chip is a bus master; in some ways it resembles
- * a DEC 'tulip' chip, only not as complicated. Unfortunately, it has
- * one major difference which is that while the registers do many of
- * the same things as a tulip adapter, the offsets are different: where
- * tulip registers are typically spaced 8 bytes apart, the Winbond
- * registers are spaced 4 bytes apart. The receiver filter is also
- * programmed differently.
- *
- * Like the tulip, the Winbond chip uses small descriptors containing
- * a status word, a control word and 32-bit areas that can either be used
- * to point to two external data blocks, or to point to a single block
- * and another descriptor in a linked list. Descriptors can be grouped
- * together in blocks to form fixed length rings or can be chained
- * together in linked lists. A single packet may be spread out over
- * several descriptors if necessary.
- *
- * For the receive ring, this driver uses a linked list of descriptors,
- * each pointing to a single mbuf cluster buffer, which us large enough
- * to hold an entire packet. The link list is looped back to created a
- * closed ring.
- *
- * For transmission, the driver creates a linked list of 'super descriptors'
- * which each contain several individual descriptors linked toghether.
- * Each 'super descriptor' contains WB_MAXFRAGS descriptors, which we
- * abuse as fragment pointers. This allows us to use a buffer managment
- * scheme very similar to that used in the ThunderLAN and Etherlink XL
- * drivers.
- *
- * Autonegotiation is performed using the external PHY via the MII bus.
- * The sample boards I have all use a Davicom PHY.
- *
- * Note: the author of the Linux driver for the Winbond chip alludes
- * to some sort of flaw in the chip's design that seems to mandate some
- * drastic workaround which signigicantly impairs transmit performance.
- * I have no idea what he's on about: transmit performance with all
- * three of my test boards seems fine.

- * A transmit 'super descriptor' is actually WB_MAXFRAGS regular
- * descriptors clumped together. The idea here is to emulate the
- * multi-fragment descriptor layout found in devices such as the
- * Texas Instruments ThunderLAN and 3Com boomerang and cylone chips.
- * The advantage to using this scheme is that it avoids buffer copies.
- * The disadvantage is that there's a certain amount of overhead due
- * to the fact that each 'fragment' is 16 bytes long. In my tests,
- * this limits top speed to about 10.5MB/sec. It should be more like
- * 11.5MB/sec. However, the upshot is that you can achieve better
- * results on slower machines: a Pentium 200 can pump out packets at
- * same speed as a PII 400.
