- Linux Kernel Additions:
-
- 0.99H+lk0.9 - David S. Miller - softnet, PCI DMA updates
- 0.99H+lk1.0 - Jeff Garzik <jgarzik@pobox.com>
- Remove compatibility defines for kernel versions < 2.2.x.
- Update for new 2.3.x module interface
- LK1.1.2 (March 19, 2000)
- * New PCI interface (jgarzik)
-
- LK1.1.3 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- - Merged with 3c575_cb.c
- - Don't set RxComplete in boomerang interrupt enable reg
- - spinlock in vortex_timer to protect mdio functions
- - disable local interrupts around call to vortex_interrupt in
- vortex_tx_timeout() (So vortex_interrupt can use spin_lock())
- - Select window 3 in vortex_timer()'s write to Wn3_MAC_Ctrl
- - In vortex_start_xmit(), move the lock to _after_ we've altered
- vp->cur_tx and vp->tx_full. This defeats the race between
- vortex_start_xmit() and vortex_interrupt which was identified
- by Bogdan Costescu.
- - Merged back support for six new cards from various sources
- - Set vortex_have_pci if pci_module_init returns zero (fixes cardbus
- insertion oops)
- - Tell it that 3c905C has NWAY for 100bT autoneg
- - Fix handling of SetStatusEnd in 'Too much work..' code, as
- per 2.3.99's 3c575_cb (Dave Hinds).
- - Split ISR into two for vortex & boomerang
- - Fix MOD_INC/DEC races
- - Handle resource allocation failures.
- - Fix 3CCFE575CT LED polarity
- - Make tx_interrupt_mitigation the default
-
- LK1.1.4 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- - Add extra TxReset to vortex_up() to fix 575_cb hotplug initialisation probs.
- - Put vortex_info_tbl into __devinitdata
- - In the vortex_error StatsFull HACK, disable stats in vp->intr_enable as well
- as in the hardware.
- - Increased the loop counter in issue_and_wait from 2,000 to 4,000.
-
- LK1.1.5 28 April 2000, andrewm
- - Added powerpc defines (John Daniel <jdaniel@etresoft.com> said these work...)
- - Some extra diagnostics
- - In vortex_error(), reset the Tx on maxCollisions. Otherwise most
- chips usually get a Tx timeout.
- - Added extra_reset module parm
- - Replaced some inline timer manip with mod_timer
- (Franois romieu <Francois.Romieu@nic.fr>)
- - In vortex_up(), don't make Wn3_config initialisation dependent upon has_nway
- (this came across from 3c575_cb).
-
- LK1.1.6 06 Jun 2000, andrewm
- - Backed out the PPC defines.
- - Use del_timer_sync(), mod_timer().
- - Fix wrapped ulong comparison in boomerang_rx()
- - Add IS_TORNADO, use it to suppress 3c905C checksum error msg
- (Donald Becker, I Lee Hetherington <ilh@sls.lcs.mit.edu>)
- - Replace union wn3_config with BFINS/BFEXT manipulation for
- sparc64 (Pete Zaitcev, Peter Jones)
- - In vortex_error, do_tx_reset and vortex_tx_timeout(Vortex):
- do a netif_wake_queue() to better recover from errors. (Anders Pedersen,
- Donald Becker)
- - Print a warning on out-of-memory (rate limited to 1 per 10 secs)
- - Added two more Cardbus 575 NICs: 5b57 and 6564 (Paul Wagland)
-
- LK1.1.7 2 Jul 2000 andrewm
- - Better handling of shared IRQs
- - Reset the transmitter on a Tx reclaim error
- - Fixed crash under OOM during vortex_open() (Mark Hemment)
- - Fix Rx cessation problem during OOM (help from Mark Hemment)
- - The spinlocks around the mdio access were blocking interrupts for 300uS.
- Fix all this to use spin_lock_bh() within mdio_read/write
- - Only write to TxFreeThreshold if it's a boomerang - other NICs don't
- have one.
- - Added 802.3x MAC-layer flow control support
-
- LK1.1.8 13 Aug 2000 andrewm
- - Ignore request_region() return value - already reserved if Cardbus.
- - Merged some additional Cardbus flags from Don's 0.99Qk
- - Some fixes for 3c556 (Fred Maciel)
- - Fix for EISA initialisation (Jan Rekorajski)
- - Renamed MII_XCVR_PWR and EEPROM_230 to align with 3c575_cb and D. Becker's drivers
- - Fixed MII_XCVR_PWR for 3CCFE575CT
- - Added INVERT_LED_PWR, used it.
- - Backed out the extra_reset stuff
-
- LK1.1.9 12 Sep 2000 andrewm
- - Backed out the tx_reset_resume flags. It was a no-op.
- - In vortex_error, don't reset the Tx on txReclaim errors
- - In vortex_error, don't reset the Tx on maxCollisions errors.
- Hence backed out all the DownListPtr logic here.
- - In vortex_error, give Tornado cards a partial TxReset on
- maxCollisions (David Hinds). Defined MAX_COLLISION_RESET for this.
- - Redid some driver flags and device names based on pcmcia_cs-3.1.20.
- - Fixed a bug where, if vp->tx_full is set when the interface
- is downed, it remains set when the interface is upped. Bad
- things happen.
-
- LK1.1.10 17 Sep 2000 andrewm
- - Added EEPROM_8BIT for 3c555 (Fred Maciel)
- - Added experimental support for the 3c556B Laptop Hurricane (Louis Gerbarg)
- - Add HAS_NWAY to "3c900 Cyclone 10Mbps TPO"
-
- LK1.1.11 13 Nov 2000 andrewm
- - Dump MOD_INC/DEC_USE_COUNT, use SET_MODULE_OWNER
-
- LK1.1.12 1 Jan 2001 andrewm (2.4.0-pre1)
- - Call pci_enable_device before we request our IRQ (Tobias Ringstrom)
- - Add 3c590 PCI latency timer hack to vortex_probe1 (from 0.99Ra)
- - Added extended issue_and_wait for the 3c905CX.
- - Look for an MII on PHY index 24 first (3c905CX oddity).
- - Add HAS_NWAY to 3cSOHO100-TX (Brett Frankenberger)
- - Don't free skbs we don't own on oom path in vortex_open().
-
- LK1.1.13 27 Jan 2001
- - Added explicit `medialock' flag so we can truly
- lock the media type down with `options'.
- - "check ioremap return and some tidbits" (Arnaldo Carvalho de Melo <acme@conectiva.com.br>)
- - Added and used EEPROM_NORESET for 3c556B PM resumes.
- - Fixed leakage of vp->rx_ring.
- - Break out separate HAS_HWCKSM device capability flag.
- - Kill vp->tx_full (ANK)
- - Merge zerocopy fragment handling (ANK?)
-
- LK1.1.14 15 Feb 2001
- - Enable WOL. Can be turned on with `enable_wol' module option.
- - EISA and PCI initialisation fixes (jgarzik, Manfred Spraul)
- - If a device's internalconfig register reports it has NWAY,
- use it, even if autoselect is enabled.
-
- LK1.1.15 6 June 2001 akpm
- - Prevent double counting of received bytes (Lars Christensen)
- - Add ethtool support (jgarzik)
- - Add module parm descriptions (Andrzej M. Krzysztofowicz)
- - Implemented alloc_etherdev() API
- - Special-case the 'Tx error 82' message.
-
- LK1.1.16 18 July 2001 akpm
- - Make NETIF_F_SG dependent upon nr_free_highpages(), not on CONFIG_HIGHMEM
- - Lessen verbosity of bootup messages
- - Fix WOL - use new PM API functions.
- - Use netif_running() instead of vp->open in suspend/resume.
- - Don't reset the interface logic on open/close/rmmod. It upsets
- autonegotiation, and hence DHCP (from 0.99T).
- - Back out EEPROM_NORESET flag because of the above (we do it for all
- NICs).
- - Correct 3c982 identification string
- - Rename wait_for_completion() to issue_and_wait() to avoid completion.h
- clash.
-
- LK1.1.17 18Dec01 akpm
- - PCI ID 9805 is a Python-T, not a dual-port Cyclone. Apparently.
- And it has NWAY.
- - Mask our advertised modes (vp->advertising) with our capabilities
- (MII reg5) when deciding which duplex mode to use.
- - Add `global_options' as default for options[]. Ditto global_enable_wol,
- global_full_duplex.
-
- LK1.1.18 01Jul02 akpm
- - Fix for undocumented transceiver power-up bit on some 3c566B's
- (Donald Becker, Rahul Karnik)
-
- - See http://www.zip.com.au/~akpm/linux/#3c59x-2.3 for more details.
- - Also see Documentation/networking/vortex.txt
-
- LK1.1.19 10Nov02 Marc Zyngier <maz@wild-wind.fr.eu.org>
- - EISA sysfs integration.

Support information and updates available at
http://www.scyld.com/network/netsemi.html
+ [link no longer provides useful info -jgarzik]
- Linux kernel modifications:
-
- Version 1.0.1:
- - Spinlock fixes
- - Bug fixes and better intr performance (Tjeerd)
- Version 1.0.2:
- - Now reads correct MAC address from eeprom
- Version 1.0.3:
- - Eliminate redundant priv->tx_full flag
- - Call netif_start_queue from dev->tx_timeout
- - wmb() in start_tx() to flush data
- - Update Tx locking
- - Clean up PCI enable (davej)
- Version 1.0.4:
- - Merge Donald Becker's natsemi.c version 1.07
- Version 1.0.5:
- - { fill me in }
- Version 1.0.6:
- * ethtool support (jgarzik)
- * Proper initialization of the card (which sometimes
- fails to occur and leaves the card in a non-functional
- state). (uzi)
-
- * Some documented register settings to optimize some
- of the 100Mbit autodetection circuitry in rev C cards. (uzi)
-
- * Polling of the PHY intr for stuff like link state
- change and auto- negotiation to finally work properly. (uzi)
-
- * One-liner removal of a duplicate declaration of
- netdev_error(). (uzi)
-
- Version 1.0.7: (Manfred Spraul)
- * pci dma
- * SMP locking update
- * full reset added into tx_timeout
- * correct multicast hash generation (both big and little endian)
- [copied from a natsemi driver version
- from Myrio Corporation, Greg Smith]
- * suspend/resume
-
- version 1.0.8 (Tim Hockin <thockin@sun.com>)
- * ETHTOOL_* support
- * Wake on lan support (Erik Gilling)
- * MXDMA fixes for serverworks
- * EEPROM reload
-
- version 1.0.9 (Manfred Spraul)
- * Main change: fix lack of synchronize
- netif_close/netif_suspend against a last interrupt
- or packet.
- * do not enable superflous interrupts (e.g. the
- drivers relies on TxDone - TxIntr not needed)
- * wait that the hardware has really stopped in close
- and suspend.
- * workaround for the (at least) gcc-2.95.1 compiler
- problem. Also simplifies the code a bit.
- * disable_irq() in tx_timeout - needed to protect
- against rx interrupts.
- * stop the nic before switching into silent rx mode
- for wol (required according to docu).
-
- version 1.0.10:
- * use long for ee_addr (various)
- * print pointers properly (DaveM)
- * include asm/irq.h (?)
-
- version 1.0.11:
- * check and reset if PHY errors appear (Adrian Sun)
- * WoL cleanup (Tim Hockin)
- * Magic number cleanup (Tim Hockin)
- * Don't reload EEPROM on every reset (Tim Hockin)
- * Save and restore EEPROM state across reset (Tim Hockin)
- * MDIO Cleanup (Tim Hockin)
- * Reformat register offsets/bits (jgarzik)
-
- version 1.0.12:
- * ETHTOOL_* further support (Tim Hockin)
-
- version 1.0.13:
- * ETHTOOL_[G]EEPROM support (Tim Hockin)
-
- version 1.0.13:
- * crc cleanup (Matt Domsch <Matt_Domsch@dell.com>)
-
- version 1.0.14:
- * Cleanup some messages and autoneg in ethtool (Tim Hockin)
-
- version 1.0.15:
- * Get rid of cable_magic flag
- * use new (National provided) solution for cable magic issue
-
- version 1.0.16:
- * call netdev_rx() for RxErrors (Manfred Spraul)
- * formatting and cleanups
- * change options and full_duplex arrays to be zero
- initialized
- * enable only the WoL and PHY interrupts in wol mode
-
- version 1.0.17:
- * only do cable_magic on 83815 and early 83816 (Tim Hockin)
- * create a function for rx refill (Manfred Spraul)
- * combine drain_ring and init_ring (Manfred Spraul)
- * oom handling (Manfred Spraul)
- * hands_off instead of playing with netif_device_{de,a}ttach
- (Manfred Spraul)
- * be sure to write the MAC back to the chip (Manfred Spraul)
- * lengthen EEPROM timeout, and always warn about timeouts
- (Manfred Spraul)
- * comments update (Manfred)
- * do the right thing on a phy-reset (Manfred and Tim)

- LK1.1.0:
- - Jeff Garzik: softnet 'n stuff
-
- LK1.1.1:
- - Justin Guyett: softnet and locking fixes
- - Jeff Garzik: use PCI interface
-
- LK1.1.2:
- - Urban Widmark: minor cleanups, merges from Becker 1.03a/1.04 versions
-
- LK1.1.3:
- - Urban Widmark: use PCI DMA interface (with thanks to the eepro100.c
- code) update "Theory of Operation" with
- softnet/locking changes
- - Dave Miller: PCI DMA and endian fixups
- - Jeff Garzik: MOD_xxx race fixes, updated PCI resource allocation
-
- LK1.1.4:
- - Urban Widmark: fix gcc 2.95.2 problem and
- remove writel's to fixed address 0x7c
-
- LK1.1.5:
- - Urban Widmark: mdio locking, bounce buffer changes
- merges from Beckers 1.05 version
- added netif_running_on/off support
-
- LK1.1.6:
- - Urban Widmark: merges from Beckers 1.08b version (VT6102 + mdio)
- set netif_running_on/off on startup, del_timer_sync
-
- LK1.1.7:
- - Manfred Spraul: added reset into tx_timeout
-
- LK1.1.9:
- - Urban Widmark: merges from Beckers 1.10 version
- (media selection + eeprom reload)
- - David Vrabel: merges from D-Link "1.11" version
- (disable WOL and PME on startup)
-
- LK1.1.10:
- - Manfred Spraul: use "singlecopy" for unaligned buffers
- don't allocate bounce buffers for !ReqTxAlign cards
-
- LK1.1.11:
- - David Woodhouse: Set dev->base_addr before the first time we call
- wait_for_reset(). It's a lot happier that way.
- Free np->tx_bufs only if we actually allocated it.
-
- LK1.1.12:
- - Martin Eriksson: Allow Memory-Mapped IO to be enabled.
-
- LK1.1.13 (jgarzik):
- - Add ethtool support
- - Replace some MII-related magic numbers with constants
-
- LK1.1.14 (Ivan G.):
- - fixes comments for Rhine-III
- - removes W_MAX_TIMEOUT (unused)
- - adds HasDavicomPhy for Rhine-I (basis: linuxfet driver; my card
- is R-I and has Davicom chip, flag is referenced in kernel driver)
- - sends chip_id as a parameter to wait_for_reset since np is not
- initialized on first call
- - changes mmio "else if (chip_id==VT6102)" to "else" so it will work
- for Rhine-III's (documentation says same bit is correct)
- - transmit frame queue message is off by one - fixed
- - adds IntrNormalSummary to "Something Wicked" exclusion list
- so normal interrupts will not trigger the message (src: Donald Becker)
- (Roger Luethi)
- - show confused chip where to continue after Tx error
- - location of collision counter is chip specific
- - allow selecting backoff algorithm (module parameter)
-
- LK1.1.15 (jgarzik):
- - Use new MII lib helper generic_mii_ioctl
-
- LK1.1.16 (Roger Luethi)
- - Etherleak fix
- - Handle Tx buffer underrun

- - Fix race in via_rhine_start_tx()
- - On errors, wait for Tx engine to turn off before scavenging
- - Handle Tx descriptor write-back race on Rhine-II
