 /* Change Log
- * 5.3.12	6/7/04
- * - kcompat NETIF_MSG for older kernels (2.4.9) <sean.p.mcdermott@intel.com>
- * - if_mii support and associated kcompat for older kernels
- * - More errlogging support from Jon Mason <jonmason@us.ibm.com>
- * - Fix TSO issues on PPC64 machines -- Jon Mason <jonmason@us.ibm.com>
- *
- * 5.7.1	12/16/04
- * - Resurrect 82547EI/GI related fix in e1000_intr to avoid deadlocks. This
- *   fix was removed as it caused system instability. The suspected cause of 
- *   this is the called to e1000_irq_disable in e1000_intr. Inlined the 
- *   required piece of e1000_irq_disable into e1000_intr - Anton Blanchard
- * 5.7.0	12/10/04
- * - include fix to the condition that determines when to quit NAPI - Robert Olsson
- * - use netif_poll_{disable/enable} to synchronize between NAPI and i/f up/down
- * 5.6.5 	11/01/04
- * - Enabling NETIF_F_SG without checksum offload is illegal - 
-     John Mason <jdmason@us.ibm.com>
- * 5.6.3        10/26/04
- * - Remove redundant initialization - Jamal Hadi
- * - Reset buffer_info->dma in tx resource cleanup logic
- * 5.6.2	10/12/04
- * - Avoid filling tx_ring completely - shemminger@osdl.org
- * - Replace schedule_timeout() with msleep()/msleep_interruptible() -
- *   nacc@us.ibm.com
- * - Sparse cleanup - shemminger@osdl.org
- * - Fix tx resource cleanup logic
- * - LLTX support - ak@suse.de and hadi@cyberus.ca
+ * 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
