134 I. Board Compatibility
136 This device driver is designed for the 3Com FastEtherLink and FastEtherLink
137 XL, 3Com's PCI to 10/100baseT adapters. It also works with the 10Mbs
138 versions of the FastEtherLink cards. The supported product IDs are
139 3c590, 3c592, 3c595, 3c597, 3c900, 3c905
141 The related ISA 3c515 is supported with a separate driver, 3c515.c, included
142 with the kernel source or available from
143 cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
145 II. Board-specific settings
147 PCI bus devices are configured by the system at boot time, so no jumpers
148 need to be set on the board. The system BIOS should be set to assign the
149 PCI INTA signal to an otherwise unused system IRQ line.
151 The EEPROM settings for media type and forced-full-duplex are observed.
152 The EEPROM media type should be left at the default "autoselect" unless using
153 10base2 or AUI connections which cannot be reliably detected.
155 III. Driver operation
157 The 3c59x series use an interface that's very similar to the previous 3c5x9
158 series. The primary interface is two programmed-I/O FIFOs, with an
159 alternate single-contiguous-region bus-master transfer (see next).
161 The 3c900 "Boomerang" series uses a full-bus-master interface with separate
162 lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
163 DEC Tulip and Intel Speedo3. The first chip version retains a compatible
164 programmed-I/O interface that has been removed in 'B' and subsequent board
167 One extension that is advertised in a very large font is that the adapters
168 are capable of being bus masters. On the Vortex chip this capability was
169 only for a single contiguous region making it far less useful than the full
170 bus master capability. There is a significant performance impact of taking
171 an extra interrupt or polling for the completion of each transfer, as well
172 as difficulty sharing the single transfer engine between the transmit and
173 receive threads. Using DMA transfers is a win only with large blocks or
174 with the flawed versions of the Intel Orion motherboard PCI controller.
176 The Boomerang chip's full-bus-master interface is useful, and has the
177 currently-unused advantages over other similar chips that queued transmit
178 packets may be reordered and receive buffer groups are associated with a
181 With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
182 Rather than a fixed intermediate receive buffer, this scheme allocates
183 full-sized skbuffs as receive buffers. The value RX_COPYBREAK is used as
184 the copying breakpoint: it is chosen to trade-off the memory wasted by
185 passing the full-sized skbuff to the queue layer for all frames vs. the
186 copying cost of copying a frame to a correctly-sized skbuff.
188 IIIC. Synchronization
189 The driver runs as two independent, single-threaded flows of control. One
190 is the send-packet routine, which enforces single-threaded use by the
191 dev->tbusy flag. The other thread is the interrupt handler, which is single
192 threaded by the hardware and other software.
196 Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
197 3c590, 3c595, and 3c900 boards.
198 The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
199 the EISA version is called "Demon". According to Terry these names come
200 from rides at the local amusement park.
202 The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
203 This driver only supports ethernet packets because of the skbuff allocation
