/* Change Log
- * 6.0.58 4/20/05
- * o Accepted ethtool cleanup patch from Stephen Hemminger
- * 6.0.44+ 2/15/05
- * o applied Anton's patch to resolve tx hang in hardware
- * o Applied Andrew Mortons patch - e1000 stops working after resume
+ * 6.3.9 12/16/2005
+ * o incorporate fix for recycled skbs from IBM LTC
+ * 6.3.7 11/18/2005
+ * o Honor eeprom setting for enabling/disabling Wake On Lan
+ * 6.3.5 11/17/2005
+ * o Fix memory leak in rx ring handling for PCI Express adapters
+ * 6.3.4 11/8/05
+ * o Patch from Jesper Juhl to remove redundant NULL checks for kfree
+ * 6.3.2 9/20/05
+ * o Render logic that sets/resets DRV_LOAD as inline functions to
+ * avoid code replication. If f/w is AMT then set DRV_LOAD only when
+ * network interface is open.
+ * o Handle DRV_LOAD set/reset in cases where AMT uses VLANs.
+ * o Adjust PBA partioning for Jumbo frames using MTU size and not
+ * rx_buffer_len
+ * 6.3.1 9/19/05
+ * o Use adapter->tx_timeout_factor in Tx Hung Detect logic
+ (e1000_clean_tx_irq)
+ * o Support for 8086:10B5 device (Quad Port)
+ * 6.2.14 9/15/05
+ * o In AMT enabled configurations, set/reset DRV_LOAD bit on interface
+ * open/close
+ * 6.2.13 9/14/05
+ * o Invoke e1000_check_mng_mode only for 8257x controllers since it
+ * accesses the FWSM that is not supported in other controllers
+ * 6.2.12 9/9/05
+ * o Add support for device id E1000_DEV_ID_82546GB_QUAD_COPPER
+ * o set RCTL:SECRC only for controllers newer than 82543.
+ * o When the n/w interface comes down reset DRV_LOAD bit to notify f/w.
+ * This code was moved from e1000_remove to e1000_close
+ * 6.2.10 9/6/05
+ * o Fix error in updating RDT in el1000_alloc_rx_buffers[_ps] -- one off.
+ * o Enable fc by default on 82573 controllers (do not read eeprom)
+ * o Fix rx_errors statistic not to include missed_packet_count
+ * o Fix rx_dropped statistic not to include missed_packet_count
+ (Padraig Brady)
+ * 6.2.9 8/30/05
+ * o Remove call to update statistics from the controller ib e1000_get_stats
+ * 6.2.8 8/30/05
+ * o Improved algorithm for rx buffer allocation/rdt update
+ * o Flow control watermarks relative to rx PBA size
+ * o Simplified 'Tx Hung' detect logic
+ * 6.2.7 8/17/05
+ * o Report rx buffer allocation failures and tx timeout counts in stats
+ * 6.2.6 8/16/05
+ * o Implement workaround for controller erratum -- linear non-tso packet
+ * following a TSO gets written back prematurely
+ * 6.2.5 8/15/05
+ * o Set netdev->tx_queue_len based on link speed/duplex settings.
+ * o Fix net_stats.rx_fifo_errors <p@draigBrady.com>
+ * o Do not power off PHY if SoL/IDER session is active
+ * 6.2.4 8/10/05
+ * o Fix loopback test setup/cleanup for 82571/3 controllers
+ * o Fix parsing of outgoing packets (e1000_transfer_dhcp_info) to treat
+ * all packets as raw
+ * o Prevent operations that will cause the PHY to be reset if SoL/IDER
+ * sessions are active and log a message
+ * 6.2.2 7/21/05
+ * o used fixed size descriptors for all MTU sizes, reduces memory load
+ * 6.1.2 4/13/05
+ * o Fixed ethtool diagnostics
+ * o Enabled flow control to take default eeprom settings
+ * o Added stats_lock around e1000_read_phy_reg commands to avoid concurrent
+ * calls, one from mii_ioctl and other from within update_stats while
+ * processing MIIREG ioctl.
