- *   o Added another fix for the pass false carrier bit
- * 7.0.32      24-Jan-2006
- *   o Need to rebuild with noew version number for the pass false carrier 
- *     fix in e1000_hw.c
- * 7.0.30      18-Jan-2006
- *   o fixup for tso workaround to disable it for pci-x
- *   o fix mem leak on 82542
- *   o fixes for 10 Mb/s connections and incorrect stats
- * 7.0.28      01/06/2006
- *   o hardware workaround to only set "speed mode" bit for 1G link.
- * 7.0.26      12/23/2005
- *   o wake on lan support modified for device ID 10B5
- *   o fix dhcp + vlan issue not making it to the iAMT firmware
- * 7.0.24      12/9/2005
- *   o New hardware support for the Gigabit NIC embedded in the south bridge
- *   o Fixes to the recycling logic (skb->tail) from IBM LTC
- * 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)
