 *	v1.1 Dec 20, 1999    - Removed linux version checking
 *			       Patch from Tigran Aivazian.
 *			     - v1.1 includes Alan's SMP updates.
 *			     - We still have problems on SMP though,
 *			       but I'm looking into that.
 *
 *	v1.2 Jan 02, 2000    - Hopefully fixed the SMP deadlock.
 *			     - Removed dependency of HZ being 100.
 *			     - We now allow higher priority timers to
 *			       overwrite timers like TLAN_TIMER_ACTIVITY
 *			       Patch from John Cagle <john.cagle@compaq.com>.
 *			     - Fixed a few compiler warnings.
 *
 *	v1.3 Feb 04, 2000    - Fixed the remaining HZ issues.
 *			     - Removed call to pci_present().
 *			     - Removed SA_INTERRUPT flag from irq handler.
 *			     - Added __init and __initdata to reduce resisdent
 *			       code size.
 *			     - Driver now uses module_init/module_exit.
 *			     - Rewrote init_module and tlan_probe to
 *			       share a lot more code. We now use tlan_probe
 *			       with builtin and module driver.
 *			     - Driver ported to new net API.
 *			     - tlan.txt has been reworked to reflect current
 *			       driver (almost)
 *			     - Other minor stuff
 *
 *	v1.4 Feb 10, 2000    - Updated with more changes required after Dave's
 *	                       network cleanup in 2.3.43pre7 (Tigran & myself)
 *	                     - Minor stuff.
 *
 *	v1.5 March 22, 2000  - Fixed another timer bug that would hang the driver
 *			       if no cable/link were present.
 *			     - Cosmetic changes.
 *			     - TODO: Port completely to new PCI/DMA API
 *			     	     Auto-Neg fallback.
 *
 * 	v1.6 April 04, 2000  - Fixed driver support for kernel-parameters. Haven't
 * 			       tested it though, as the kernel support is currently
 * 			       broken (2.3.99p4p3).
 * 			     - Updated tlan.txt accordingly.
 * 			     - Adjusted minimum/maximum frame length.
 * 			     - There is now a TLAN website up at
 * 			       http://tlan.kernel.dk
 *
 * 	v1.7 April 07, 2000  - Started to implement custom ioctls. Driver now
 * 			       reports PHY information when used with Donald
 * 			       Beckers userspace MII diagnostics utility.
 *
 * 	v1.8 April 23, 2000  - Fixed support for forced speed/duplex settings.
 * 			     - Added link information to Auto-Neg and forced
 * 			       modes. When NIC operates with auto-neg the driver
 * 			       will report Link speed & duplex modes as well as
 * 			       link partner abilities. When forced link is used,
 * 			       the driver will report status of the established
 * 			       link.
 * 			       Please read tlan.txt for additional information.
 * 			     - Removed call to check_region(), and used
 * 			       return value of request_region() instead.
 *
 *	v1.8a May 28, 2000   - Minor updates.
 *
 *	v1.9 July 25, 2000   - Fixed a few remaining Full-Duplex issues.
 *	                     - Updated with timer fixes from Andrew Morton.
 *	                     - Fixed module race in TLan_Open.
 *	                     - Added routine to monitor PHY status.
 *	                     - Added activity led support for Proliant devices.
 *
 *	v1.10 Aug 30, 2000   - Added support for EISA based tlan controllers
 *			       like the Compaq NetFlex3/E.
 *			     - Rewrote tlan_probe to better handle multiple
 *			       bus probes. Probing and device setup is now
 *			       done through TLan_Probe and TLan_init_one. Actual
 *			       hardware probe is done with kernel API and
 *			       TLan_EisaProbe.
 *			     - Adjusted debug information for probing.
 *			     - Fixed bug that would cause general debug information
 *			       to be printed after driver removal.
 *			     - Added transmit timeout handling.
 *			     - Fixed OOM return values in tlan_probe.
 *			     - Fixed possible mem leak in tlan_exit
 *			       (now tlan_remove_one).
 *			     - Fixed timer bug in TLan_phyMonitor.
 *			     - This driver version is alpha quality, please
 *			       send me any bug issues you may encounter.
 *
 *	v1.11 Aug 31, 2000   - Do not try to register irq 0 if no irq line was
 *			       set for EISA cards.
 *			     - Added support for NetFlex3/E with nibble-rate
 *			       10Base-T PHY. This is untestet as I haven't got
 *			       one of these cards.
 *			     - Fixed timer being added twice.
 *			     - Disabled PhyMonitoring by default as this is
 *			       work in progress. Define MONITOR to enable it.
 *			     - Now we don't display link info with PHYs that
 *			       doesn't support it (level1).
 *			     - Incresed tx_timeout beacuse of auto-neg.
 *			     - Adjusted timers for forced speeds.
 *
 *	v1.12 Oct 12, 2000   - Minor fixes (memleak, init, etc.)
 *
 * 	v1.13 Nov 28, 2000   - Stop flooding console with auto-neg issues
 * 			       when link can't be established.
 *			     - Added the bbuf option as a kernel parameter.
 *			     - Fixed ioaddr probe bug.
 *			     - Fixed stupid deadlock with MII interrupts.
 *			     - Added support for speed/duplex selection with
 *			       multiple nics.
 *			     - Added partly fix for TX Channel lockup with
 *			       TLAN v1.0 silicon. This needs to be investigated
 *			       further.
 *
 * 	v1.14 Dec 16, 2000   - Added support for servicing multiple frames per.
 * 			       interrupt. Thanks goes to
 * 			       Adam Keys <adam@ti.com>
 * 			       Denis Beaudoin <dbeaudoin@ti.com>
 * 			       for providing the patch.
 * 			     - Fixed auto-neg output when using multiple
 * 			       adapters.
 * 			     - Converted to use new taskq interface.
 *
 * 	v1.14a Jan 6, 2001   - Minor adjustments (spinlocks, etc.)
 *
 *	Samuel Chessman <chessman@tux.org> New Maintainer!
 *
 *	v1.15 Apr 4, 2002    - Correct operation when aui=1 to be
 *	                       10T half duplex no loopback
 *	                       Thanks to Gunnar Eikman
 *
 *	Sakari Ailus <sakari.ailus@iki.fi>:
 *
 *	v1.15a Dec 15 2008   - Remove bbuf support, it doesn't work anyway.

	 *	in the channel (EOC), then the function checks to see if
	 *	another buffer is ready to send, and if so, sends a Tx
	 *	Go command.  Finally, the driver activates/continues the
