* 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.
+ * - 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.)

- * pci_dfn The PCI whatever the card was

- * pci_irq The IRQ of the found adapter.
- * pci_rev The revision of the adapter.
- * pci_io_base The first IO port used by the

- * dl_ix The index in the device list

- * This function searches for an adapter with PCI vendor

- * The function 'remembers' the last device it found,

- * each time the function is called. It then looks up
- * pertinent PCI info and returns it to the caller.
