-		- 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)
-

-		* 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).

-	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.
