20 Linux Kernel Additions:
22 0.99H+lk0.9 - David S. Miller - softnet, PCI DMA updates
23 0.99H+lk1.0 - Jeff Garzik <jgarzik@pobox.com>
24 Remove compatibility defines for kernel versions < 2.2.x.
25 Update for new 2.3.x module interface
26 LK1.1.2 (March 19, 2000)
27 * New PCI interface (jgarzik)
29 LK1.1.3 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
30 - Merged with 3c575_cb.c
31 - Don't set RxComplete in boomerang interrupt enable reg
32 - spinlock in vortex_timer to protect mdio functions
33 - disable local interrupts around call to vortex_interrupt in
34 vortex_tx_timeout() (So vortex_interrupt can use spin_lock())
35 - Select window 3 in vortex_timer()'s write to Wn3_MAC_Ctrl
36 - In vortex_start_xmit(), move the lock to _after_ we've altered
37 vp->cur_tx and vp->tx_full. This defeats the race between
38 vortex_start_xmit() and vortex_interrupt which was identified
40 - Merged back support for six new cards from various sources
41 - Set vortex_have_pci if pci_module_init returns zero (fixes cardbus
43 - Tell it that 3c905C has NWAY for 100bT autoneg
44 - Fix handling of SetStatusEnd in 'Too much work..' code, as
45 per 2.3.99's 3c575_cb (Dave Hinds).
46 - Split ISR into two for vortex & boomerang
47 - Fix MOD_INC/DEC races
48 - Handle resource allocation failures.
49 - Fix 3CCFE575CT LED polarity
50 - Make tx_interrupt_mitigation the default
52 LK1.1.4 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
53 - Add extra TxReset to vortex_up() to fix 575_cb hotplug initialisation probs.
54 - Put vortex_info_tbl into __devinitdata
55 - In the vortex_error StatsFull HACK, disable stats in vp->intr_enable as well
57 - Increased the loop counter in issue_and_wait from 2,000 to 4,000.
59 LK1.1.5 28 April 2000, andrewm
60 - Added powerpc defines (John Daniel <jdaniel@etresoft.com> said these work...)
61 - Some extra diagnostics
62 - In vortex_error(), reset the Tx on maxCollisions. Otherwise most
63 chips usually get a Tx timeout.
64 - Added extra_reset module parm
65 - Replaced some inline timer manip with mod_timer
66 (Franois romieu <Francois.Romieu@nic.fr>)
67 - In vortex_up(), don't make Wn3_config initialisation dependent upon has_nway
68 (this came across from 3c575_cb).
70 LK1.1.6 06 Jun 2000, andrewm
71 - Backed out the PPC defines.
72 - Use del_timer_sync(), mod_timer().
73 - Fix wrapped ulong comparison in boomerang_rx()

81 - Print a warning on out-of-memory (rate limited to 1 per 10 secs)
82 - Added two more Cardbus 575 NICs: 5b57 and 6564 (Paul Wagland)
84 LK1.1.7 2 Jul 2000 andrewm
85 - Better handling of shared IRQs
86 - Reset the transmitter on a Tx reclaim error
87 - Fixed crash under OOM during vortex_open() (Mark Hemment)
88 - Fix Rx cessation problem during OOM (help from Mark Hemment)
89 - The spinlocks around the mdio access were blocking interrupts for 300uS.
90 Fix all this to use spin_lock_bh() within mdio_read/write
91 - Only write to TxFreeThreshold if it's a boomerang - other NICs don't
93 - Added 802.3x MAC-layer flow control support
95 LK1.1.8 13 Aug 2000 andrewm

102 - Added INVERT_LED_PWR, used it.
103 - Backed out the extra_reset stuff
105 LK1.1.9 12 Sep 2000 andrewm
106 - Backed out the tx_reset_resume flags. It was a no-op.
107 - In vortex_error, don't reset the Tx on txReclaim errors
108 - In vortex_error, don't reset the Tx on maxCollisions errors.
109 Hence backed out all the DownListPtr logic here.
110 - In vortex_error, give Tornado cards a partial TxReset on
111 maxCollisions (David Hinds). Defined MAX_COLLISION_RESET for this.
112 - Redid some driver flags and device names based on pcmcia_cs-3.1.20.
113 - Fixed a bug where, if vp->tx_full is set when the interface
114 is downed, it remains set when the interface is upped. Bad
117 LK1.1.10 17 Sep 2000 andrewm
118 - Added EEPROM_8BIT for 3c555 (Fred Maciel)

136 - "check ioremap return and some tidbits" (Arnaldo Carvalho de Melo <acme@conectiva.com.br>)
137 - Added and used EEPROM_NORESET for 3c556B PM resumes.
138 - Fixed leakage of vp->rx_ring.
139 - Break out separate HAS_HWCKSM device capability flag.
140 - Kill vp->tx_full (ANK)

159 - Fix WOL - use new PM API functions.
160 - Use netif_running() instead of vp->open in suspend/resume.
161 - Don't reset the interface logic on open/close/rmmod. It upsets
162 autonegotiation, and hence DHCP (from 0.99T).
163 - Back out EEPROM_NORESET flag because of the above (we do it for all
165 - Correct 3c982 identification string
166 - Rename wait_for_completion() to issue_and_wait() to avoid completion.h
169 LK1.1.17 18Dec01 akpm
170 - PCI ID 9805 is a Python-T, not a dual-port Cyclone. Apparently.
172 - Mask our advertised modes (vp->advertising) with our capabilities
173 (MII reg5) when deciding which duplex mode to use.
174 - Add `global_options' as default for options[]. Ditto global_enable_wol,
177 LK1.1.18 01Jul02 akpm
178 - Fix for undocumented transceiver power-up bit on some 3c566B's
179 (Donald Becker, Rahul Karnik)
181 - See http://www.zip.com.au/~akpm/linux/#3c59x-2.3 for more details.
182 - Also see Documentation/networking/vortex.txt
184 LK1.1.19 10Nov02 Marc Zyngier <maz@wild-wind.fr.eu.org>
185 - EISA sysfs integration.
189 * FIXME: This driver _could_ support MTU changing, but doesn't. See Don's hamachi.c implementation
190 * as well as other drivers
192 * NOTE: If you make 'vortex_debug' a constant (#define vortex_debug 0) the driver shrinks by 2k
193 * due to dead code elimination. There will be some performance benefits from this due to
194 * elimination of all the tests and reduced cache footprint.

305 I. Board Compatibility
307 This device driver is designed for the 3Com FastEtherLink and FastEtherLink
308 XL, 3Com's PCI to 10/100baseT adapters. It also works with the 10Mbs
309 versions of the FastEtherLink cards. The supported product IDs are
310 3c590, 3c592, 3c595, 3c597, 3c900, 3c905
312 The related ISA 3c515 is supported with a separate driver, 3c515.c, included
313 with the kernel source or available from
314 cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
316 II. Board-specific settings
318 PCI bus devices are configured by the system at boot time, so no jumpers
319 need to be set on the board. The system BIOS should be set to assign the
320 PCI INTA signal to an otherwise unused system IRQ line.
322 The EEPROM settings for media type and forced-full-duplex are observed.
323 The EEPROM media type should be left at the default "autoselect" unless using
324 10base2 or AUI connections which cannot be reliably detected.
326 III. Driver operation
328 The 3c59x series use an interface that's very similar to the previous 3c5x9
329 series. The primary interface is two programmed-I/O FIFOs, with an
330 alternate single-contiguous-region bus-master transfer (see next).
332 The 3c900 "Boomerang" series uses a full-bus-master interface with separate
333 lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
334 DEC Tulip and Intel Speedo3. The first chip version retains a compatible
335 programmed-I/O interface that has been removed in 'B' and subsequent board
338 One extension that is advertised in a very large font is that the adapters
339 are capable of being bus masters. On the Vortex chip this capability was
340 only for a single contiguous region making it far less useful than the full
341 bus master capability. There is a significant performance impact of taking
342 an extra interrupt or polling for the completion of each transfer, as well
343 as difficulty sharing the single transfer engine between the transmit and
344 receive threads. Using DMA transfers is a win only with large blocks or
345 with the flawed versions of the Intel Orion motherboard PCI controller.
347 The Boomerang chip's full-bus-master interface is useful, and has the
348 currently-unused advantages over other similar chips that queued transmit
349 packets may be reordered and receive buffer groups are associated with a
352 With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
353 Rather than a fixed intermediate receive buffer, this scheme allocates
354 full-sized skbuffs as receive buffers. The value RX_COPYBREAK is used as
355 the copying breakpoint: it is chosen to trade-off the memory wasted by
356 passing the full-sized skbuff to the queue layer for all frames vs. the
357 copying cost of copying a frame to a correctly-sized skbuff.
359 IIIC. Synchronization
360 The driver runs as two independent, single-threaded flows of control. One
361 is the send-packet routine, which enforces single-threaded use by the
362 dev->tbusy flag. The other thread is the interrupt handler, which is single
363 threaded by the hardware and other software.
367 Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
368 3c590, 3c595, and 3c900 boards.
369 The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
370 the EISA version is called "Demon". According to Terry these names come
371 from rides at the local amusement park.
373 The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
374 This driver only supports ethernet packets because of the skbuff allocation
