/* 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
