[netdrvr] forcedeth: internal simplifications; changelog removal

Browse Source 
* remove changelog from source; its kept in git repository

* consolidate descriptor version tests using nv_optimized()

* consolidate NIC DMA start, stop and drain into
  nv_start_txrx(), nv_stop_txrx(), nv_drain_txrx()

*
* Changelog:
* 0.01: 05 Oct 2003: First release that compiles without warnings.
* 0.02: 05 Oct 2003: Fix bug for nv_drain_tx: do not try to free NULL skbs.
* Check all PCI BARs for the register window.
* udelay added to mii_rw.
* 0.03: 06 Oct 2003: Initialize dev->irq.
* 0.04: 07 Oct 2003: Initialize np->lock, reduce handled irqs, add printks.
* 0.05: 09 Oct 2003: printk removed again, irq status print tx_timeout.
* 0.06: 10 Oct 2003: MAC Address read updated, pff flag generation updated,
* irq mask updated
* 0.07: 14 Oct 2003: Further irq mask updates.
* 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.
* 0.10: 20 Oct 2003: First cleanup for release.
* 0.11: 21 Oct 2003: hexdump for tx added, rx buffer sizes increased.
* MAC Address init fix, set_multicast cleanup.
* 0.12: 23 Oct 2003: Cleanups for release.
* 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.
* 0.16: 15 Nov 2003: include file cleanup for ppc64, rx buffer size
* 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
* addresses, really stop rx if already running
* 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
* 0.25: 09 Mar 2004: wol support
* 0.26: 03 Jun 2004: netdriver specific annotation, sparse-related fixes
* 0.27: 19 Jun 2004: Gigabit support, new descriptor rings,
* added CK804/MCP04 device IDs, code fixes
* for registers, link status and other minor fixes.
* 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.
* 0.31: 14 Nov 2004: ethtool support for getting/setting link
* capabilities.
* 0.32: 16 Apr 2005: RX_ERROR4 handling added.
* 0.33: 16 May 2005: Support for MCP51 added.
* 0.34: 18 Jun 2005: Add DEV_NEED_LINKTIMER to all nForce nics.

* 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.

* 0.56: 22 Mar 2006: Additional ethtool config and moduleparam support.
* 0.57: 14 May 2006: Mac address set in probe/remove and order corrections.
* 0.58: 30 Oct 2006: Added support for sideband management unit.
* 0.59: 30 Oct 2006: Added support for recoverable error.
* 0.60: 20 Jan 2007: Code optimizations for rings, rx & tx data paths, and stats.
*
* 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
