/* 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
