-/* Change Log
- * 6.0.58 4/20/05
- * o iegbe_set_spd_dplx tests for compatible speed/duplex specification
- * for fiber adapters
- * 6.0.57 4/19/05
- * o Added code to fix register test failure for devices >= 82571
- *
- * 6.0.52 3/15/05
- * o Added stats_lock around iegbe_read_phy_reg commands to avoid concurrent
- * calls, one from mii_ioctl and other from within update_stats while
- * processing MIIREG ioctl.
- *
- * 6.1.2 4/13/05
- * o Fixed ethtool diagnostics
- * o Enabled flow control to take default eeprom settings
- * o Added stats_lock around iegbe_read_phy_reg commands to avoid concurrent
- * calls, one from mii_ioctl and other from within update_stats while processing
- * MIIREG ioctl.
- * 6.0.55 3/23/05
- * o Support for MODULE_VERSION
- * o Fix APM setting for 82544 based adapters
- * 6.0.54 3/26/05
- * o Added a timer to expire packets that were deferred for cleanup
- * 6.0.52 3/15/05
- * o Added stats_lock around iegbe_read_phy_reg commands to avoid concurrent
- * calls, one from mii_ioctl and other from within update_stats while
- * processing MIIREG ioctl.
- * 6.0.47 3/2/05
- * o Added enhanced functionality to the loopback diags to wrap the
- * descriptor rings
- * o Added manageability vlan filtering workaround.
- *
- * 6.0.44+ 2/15/05
- * o Added code to handle raw packet based DHCP packets
- * o Added code to fix the errata 10 buffer overflow issue
- * o Sync up with WR01-05
- * o applied Anton's patch to resolve tx hang in hardware
- * o iegbe timeouts with early writeback patch
- * o Removed Queensport IDs
- * o fixed driver panic if MAC receives a bad large packets when packet
- * split is enabled
- * o Applied Andrew Mortons patch - iegbe stops working after resume
- * 5.2.29 12/24/03
- * o Bug fix: Endianess issue causing ethtool diags to fail on ppc.
- * o Bug fix: Use pdev->irq instead of netdev->irq for MSI support.
- * o Report driver message on user override of InterruptThrottleRate module
- * parameter.
- * o Bug fix: Change I/O address storage from uint32_t to unsigned long.
- * o Feature: Added ethtool RINGPARAM support.
- * o Feature: Added netpoll support.
- * o Bug fix: Race between Tx queue and Tx clean fixed with a spin lock.
- * o Bug fix: Allow 1000/Full setting for autoneg param for fiber connections.
- * Jon D Mason [jonmason@us.ibm.com].
- *
- * 5.2.22 10/15/03
- * o Bug fix: SERDES devices might be connected to a back-plane switch that
- * doesn't support auto-neg, so add the capability to force 1000/Full.
- * Also, since forcing 1000/Full, sample RxSynchronize bit to detect link
- * state.
- * o Bug fix: Flow control settings for hi/lo watermark didn't consider
- * changes in the RX FIFO size, which could occur with Jumbo Frames or with
- * the reduced FIFO in 82547.
- * o Bug fix: Better propagation of error codes.
- * [Janice Girouard (janiceg -a-t- us.ibm.com)]
- * o Bug fix: hang under heavy Tx stress when running out of Tx descriptors;
- * wasn't clearing context descriptor when backing out of send because of
- * no-resource condition.
- * o Bug fix: check netif_running in dev->poll so we don't have to hang in
- * dev->close until all polls are finished. [Rober Olsson
- * (robert.olsson@data.slu.se)].
- * o Revert TxDescriptor ring size back to 256 since change to 1024 wasn't
- * accepted into the kernel.
- *
- * 5.2.16 8/8/03
