Support information and updates available at

[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)
TODO:
* big endian support with CFG:BEM instead of cpu_to_le32

* 970503 v0.93: Fixed auto-irq failure on warm reboot (JB)
* 970623 v1.00: First kernel version (AM)
* 970814 v1.01: Added detection of onboard receive buffer size (AM)
* 060611 v1.02: slight cleanup: email addresses, driver modernization.
* Bugs:

* - not SMP-safe (no locking of I/O accesses)
* - Note that you have to patch ifconfig for the new /proc/net/dev

Linux kernel version history:
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 bugs in full duplex handling
- New reset code uses "force reset" cmd on Rhine-II
- Various clean ups
LK1.1.17 (Roger Luethi)
- 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
- Force flushing for PCI posted writes
- More reset code changes
LK1.1.18 (Roger Luethi)
- No filtering multicast in promisc mode (Edward Peng)
- Fix for Rhine-I Tx timeouts
LK1.1.19 (Roger Luethi)
- Increase Tx threshold for unspecified errors
LK1.2.0-2.6 (Roger Luethi)
- Massive clean-up
- Rewrite PHY, media handling (remove options, full_duplex, backoff)
- Fix Tx engine race for good
- Craig Brind: Zero padded aligned buffers for short packets.
