| 811 | -/* Change Log |
| 812 | - * 6.0.58 4/20/05 |
| 813 | - * o iegbe_set_spd_dplx tests for compatible speed/duplex specification |
| 814 | - * for fiber adapters |
| 815 | - * 6.0.57 4/19/05 |
| 816 | - * o Added code to fix register test failure for devices >= 82571 |
| 817 | - * |
| 818 | - * 6.0.52 3/15/05 |
| 819 | - * o Added stats_lock around iegbe_read_phy_reg commands to avoid concurrent |
| 820 | - * calls, one from mii_ioctl and other from within update_stats while |
| 821 | - * processing MIIREG ioctl. |
| 822 | - * |
| 823 | - * 6.1.2 4/13/05 |
| 824 | - * o Fixed ethtool diagnostics |
| 825 | - * o Enabled flow control to take default eeprom settings |
| 826 | - * o Added stats_lock around iegbe_read_phy_reg commands to avoid concurrent |
| 827 | - * calls, one from mii_ioctl and other from within update_stats while processing |
| 828 | - * MIIREG ioctl. |
| 829 | - * 6.0.55 3/23/05 |
| 830 | - * o Support for MODULE_VERSION |
| 831 | - * o Fix APM setting for 82544 based adapters |
| 832 | - * 6.0.54 3/26/05 |
| 833 | - * o Added a timer to expire packets that were deferred for cleanup |
| 834 | - * 6.0.52 3/15/05 |
| 835 | - * o Added stats_lock around iegbe_read_phy_reg commands to avoid concurrent |
| 836 | - * calls, one from mii_ioctl and other from within update_stats while |
| 837 | - * processing MIIREG ioctl. |
| 838 | - * 6.0.47 3/2/05 |
| 839 | - * o Added enhanced functionality to the loopback diags to wrap the |
| 840 | - * descriptor rings |
| 841 | - * o Added manageability vlan filtering workaround. |
| 842 | - * |
| 843 | - * 6.0.44+ 2/15/05 |
| 844 | - * o Added code to handle raw packet based DHCP packets |
| 845 | - * o Added code to fix the errata 10 buffer overflow issue |
| 846 | - * o Sync up with WR01-05 |
| 847 | - * o applied Anton's patch to resolve tx hang in hardware |
| 848 | - * o iegbe timeouts with early writeback patch |
| 849 | - * o Removed Queensport IDs |
| 850 | - * o fixed driver panic if MAC receives a bad large packets when packet |
| 851 | - * split is enabled |
| 852 | - * o Applied Andrew Mortons patch - iegbe stops working after resume |
| 853 | - * 5.2.29 12/24/03 |
| 854 | - * o Bug fix: Endianess issue causing ethtool diags to fail on ppc. |
| 855 | - * o Bug fix: Use pdev->irq instead of netdev->irq for MSI support. |
| 856 | - * o Report driver message on user override of InterruptThrottleRate module |
| 857 | - * parameter. |
| 858 | - * o Bug fix: Change I/O address storage from uint32_t to unsigned long. |
| 859 | - * o Feature: Added ethtool RINGPARAM support. |
| 860 | - * o Feature: Added netpoll support. |
| 861 | - * o Bug fix: Race between Tx queue and Tx clean fixed with a spin lock. |
| 862 | - * o Bug fix: Allow 1000/Full setting for autoneg param for fiber connections. |
| 863 | - * Jon D Mason [jonmason@us.ibm.com]. |
| 864 | - * |
| 865 | - * 5.2.22 10/15/03 |
| 866 | - * o Bug fix: SERDES devices might be connected to a back-plane switch that |
| 867 | - * doesn't support auto-neg, so add the capability to force 1000/Full. |
| 868 | - * Also, since forcing 1000/Full, sample RxSynchronize bit to detect link |
| 869 | - * state. |
| 870 | - * o Bug fix: Flow control settings for hi/lo watermark didn't consider |
| 871 | - * changes in the RX FIFO size, which could occur with Jumbo Frames or with |
| 872 | - * the reduced FIFO in 82547. |
| 873 | - * o Bug fix: Better propagation of error codes. |
| 874 | - * [Janice Girouard (janiceg -a-t- us.ibm.com)] |
| 875 | - * o Bug fix: hang under heavy Tx stress when running out of Tx descriptors; |
| 876 | - * wasn't clearing context descriptor when backing out of send because of |
| 877 | - * no-resource condition. |
| 878 | - * o Bug fix: check netif_running in dev->poll so we don't have to hang in |
| 879 | - * dev->close until all polls are finished. [Rober Olsson |
| 880 | - * (robert.olsson@data.slu.se)]. |
| 881 | - * o Revert TxDescriptor ring size back to 256 since change to 1024 wasn't |
| 882 | - * accepted into the kernel. |
| 883 | - * |
| 884 | - * 5.2.16 8/8/03 |
