 Changes in version 1.3.0:
 
-* Added Intel e100 ethernet driver.
+* Added Intel PRO/100 ethernet driver (e100).
+* Added ethernet driver for NVIDIA nForce chipsets (forcedeth).
 * Removed "ec_eoeif_count" master module parameter.
 * Introduced "device IDs" to tell a master to wait for certain ethernet
   devices.

+ * 	0.08: 20 Oct 2003: rx_desc.Length initialization added, nv_alloc_rx refill
+ * 			   added into irq handler, NULL check for drain_ring.
+ * 	0.09: 20 Oct 2003: Basic link speed irq implementation. Only handle the
+ * 			   requested interrupt sources.

+ * 	0.13: 25 Oct 2003: Limit for concurrent tx packets increased to 10.
+ * 			   Set link speed correctly. start rx before starting
+ * 			   tx (nv_start_rx sets the link speed).
+ * 	0.14: 25 Oct 2003: Nic dependant irq mask.
+ * 	0.15: 08 Nov 2003: fix smp deadlock with set_multicast_list during
+ * 			   open.

+ * 			   increased to 1628 bytes.
+ * 	0.17: 16 Nov 2003: undo rx buffer size increase. Substract 1 from
+ * 			   the tx length.
+ * 	0.18: 17 Nov 2003: fix oops due to late initialization of dev_stats
+ * 	0.19: 29 Nov 2003: Handle RxNoBuf, detect & handle invalid mac

+ * 			   in nv_start_rx, clean up a bit.
+ * 	0.20: 07 Dec 2003: alloc fixes
+ * 	0.21: 12 Jan 2004: additional alloc fix, nic polling fix.
+ *	0.22: 19 Jan 2004: reprogram timer to a sane rate, avoid lockup
+ *			   on close.
+ *	0.23: 26 Jan 2004: various small cleanups
+ *	0.24: 27 Feb 2004: make driver even less anonymous in backtraces

+ *	0.26: 03 Jun 2004: netdriver specific annotation, sparse-related fixes
+ *	0.27: 19 Jun 2004: Gigabit support, new descriptor rings,

+ *	0.28: 21 Jun 2004: Big cleanup, making driver mostly endian safe
+ *	0.29: 31 Aug 2004: Add backup timer for link change notification.
+ *	0.30: 25 Sep 2004: rx checksum support for nf 250 Gb. Add rx reset
+ *			   into nv_close, otherwise reenabling for wol can
+ *			   cause DMA to kfree'd memory.

+ *			   capabilities.
+ *	0.32: 16 Apr 2005: RX_ERROR4 handling added.

+ *	0.34: 18 Jun 2005: Add DEV_NEED_LINKTIMER to all nForce nics.
+ *	0.35: 26 Jun 2005: Support for MCP55 added.
+ *	0.36: 28 Jun 2005: Add jumbo frame support.
+ *	0.37: 10 Jul 2005: Additional ethtool support, cleanup of pci id list
+ *	0.38: 16 Jul 2005: tx irq rewrite: Use global flags instead of
+ *			   per-packet flags.
+ *	0.39: 18 Jul 2005: Add 64bit descriptor support.
+ *	0.40: 19 Jul 2005: Add support for mac address change.
+ *	0.41: 30 Jul 2005: Write back original MAC in nv_close instead
+ *			   of nv_remove
+ *	0.42: 06 Aug 2005: Fix lack of link speed initialization
+ *			   in the second (and later) nv_open call
+ *	0.43: 10 Aug 2005: Add support for tx checksum.
+ *	0.44: 20 Aug 2005: Add support for scatter gather and segmentation.
+ *	0.45: 18 Sep 2005: Remove nv_stop/start_rx from every link check
+ *	0.46: 20 Oct 2005: Add irq optimization modes.
+ *	0.47: 26 Oct 2005: Add phyaddr 0 in phy scan.
+ *	0.48: 24 Dec 2005: Disable TSO, bugfix for pci_map_single
+ *	0.49: 10 Dec 2005: Fix tso for large buffers.
+ *	0.50: 20 Jan 2006: Add 8021pq tagging support.
+ *	0.51: 20 Jan 2006: Add 64bit consistent memory allocation for rings.
+ *	0.52: 20 Jan 2006: Add MSI/MSIX support.
+ *	0.53: 19 Mar 2006: Fix init from low power mode and add hw reset.
+ *	0.54: 21 Mar 2006: Fix spin locks for multi irqs and cleanup.
+ *
+ * Known bugs:
+ * We suspect that on some hardware no TX done interrupts are generated.
+ * This means recovery from netif_stop_queue only happens if the hw timer
+ * interrupt fires (100 times/second, configurable with NVREG_POLL_DEFAULT)
+ * and the timer is active in the IRQMask, or if a rx packet arrives by chance.
+ * If your hardware reliably generates tx done interrupts, then you can remove
+ * DEV_NEED_TIMERIRQ from the driver_data flags.
+ * DEV_NEED_TIMERIRQ will not harm you on sane hardware, only generating a few
+ * superfluous timer interrupts from the nic.

+ * 	0.13: 25 Oct 2003: Limit for concurrent tx packets increased to 10.
+ * 			   Set link speed correctly. start rx before starting
+ * 			   tx (nv_start_rx sets the link speed).
+ * 	0.14: 25 Oct 2003: Nic dependant irq mask.
+ * 	0.15: 08 Nov 2003: fix smp deadlock with set_multicast_list during
+ * 			   open.

+ * 			   the tx length.
+ * 	0.18: 17 Nov 2003: fix oops due to late initialization of dev_stats
+ * 	0.19: 29 Nov 2003: Handle RxNoBuf, detect & handle invalid mac

+ * 	0.21: 12 Jan 2004: additional alloc fix, nic polling fix.
+ *	0.22: 19 Jan 2004: reprogram timer to a sane rate, avoid lockup
+ *			   on close.
+ *	0.23: 26 Jan 2004: various small cleanups
+ *	0.24: 27 Feb 2004: make driver even less anonymous in backtraces

+ *	0.29: 31 Aug 2004: Add backup timer for link change notification.
+ *	0.30: 25 Sep 2004: rx checksum support for nf 250 Gb. Add rx reset
+ *			   into nv_close, otherwise reenabling for wol can
+ *			   cause DMA to kfree'd memory.
+ *	0.31: 14 Nov 2004: ethtool support for getting/setting link
+ *			   capabilities.
+ *	0.32: 16 Apr 2005: RX_ERROR4 handling added.

+ *	0.34: 18 Jun 2005: Add DEV_NEED_LINKTIMER to all nForce nics.
+ *	0.35: 26 Jun 2005: Support for MCP55 added.
+ *	0.36: 28 Jun 2005: Add jumbo frame support.
+ *	0.37: 10 Jul 2005: Additional ethtool support, cleanup of pci id list
+ *	0.38: 16 Jul 2005: tx irq rewrite: Use global flags instead of
+ *			   per-packet flags.
+ *	0.39: 18 Jul 2005: Add 64bit descriptor support.
+ *	0.40: 19 Jul 2005: Add support for mac address change.
+ *	0.41: 30 Jul 2005: Write back original MAC in nv_close instead
+ *			   of nv_remove
+ *	0.42: 06 Aug 2005: Fix lack of link speed initialization
+ *			   in the second (and later) nv_open call
+ *	0.43: 10 Aug 2005: Add support for tx checksum.

+ *	0.46: 20 Oct 2005: Add irq optimization modes.
+ *	0.47: 26 Oct 2005: Add phyaddr 0 in phy scan.
+ *	0.48: 24 Dec 2005: Disable TSO, bugfix for pci_map_single
+ *	0.49: 10 Dec 2005: Fix tso for large buffers.
+ *	0.50: 20 Jan 2006: Add 8021pq tagging support.

+ *	0.53: 19 Mar 2006: Fix init from low power mode and add hw reset.
+ *	0.54: 21 Mar 2006: Fix spin locks for multi irqs and cleanup.
+ *
+ * Known bugs:
+ * We suspect that on some hardware no TX done interrupts are generated.
+ * This means recovery from netif_stop_queue only happens if the hw timer
+ * interrupt fires (100 times/second, configurable with NVREG_POLL_DEFAULT)
+ * and the timer is active in the IRQMask, or if a rx packet arrives by chance.
+ * If your hardware reliably generates tx done interrupts, then you can remove
+ * DEV_NEED_TIMERIRQ from the driver_data flags.
+ * DEV_NEED_TIMERIRQ will not harm you on sane hardware, only generating a few
+ * superfluous timer interrupts from the nic.
