32 * 5.3.12 6/7/04 32 * 6.0.44+ 2/15/05
33 * - kcompat NETIF_MSG for older kernels (2.4.9) <sean.p.mcdermott@intel.com> 33 * o applied Anton's patch to resolve tx hang in hardware
34 * - if_mii support and associated kcompat for older kernels 34 * o Applied Andrew Mortons patch - e1000 stops working after resume
35 * - More errlogging support from Jon Mason <jonmason@us.ibm.com>
36 * - Fix TSO issues on PPC64 machines -- Jon Mason <jonmason@us.ibm.com>
37 *
38 * 5.7.1 12/16/04
39 * - Resurrect 82547EI/GI related fix in e1000_intr to avoid deadlocks. This
40 * fix was removed as it caused system instability. The suspected cause of
41 * this is the called to e1000_irq_disable in e1000_intr. Inlined the
42 * required piece of e1000_irq_disable into e1000_intr - Anton Blanchard
43 * 5.7.0 12/10/04
44 * - include fix to the condition that determines when to quit NAPI - Robert Olsson
45 * - use netif_poll_{disable/enable} to synchronize between NAPI and i/f up/down
46 * 5.6.5 11/01/04
47 * - Enabling NETIF_F_SG without checksum offload is illegal -
48 John Mason <jdmason@us.ibm.com>
49 * 5.6.3 10/26/04
50 * - Remove redundant initialization - Jamal Hadi
51 * - Reset buffer_info->dma in tx resource cleanup logic
52 * 5.6.2 10/12/04
53 * - Avoid filling tx_ring completely - shemminger@osdl.org
54 * - Replace schedule_timeout() with msleep()/msleep_interruptible() -
55 * nacc@us.ibm.com
56 * - Sparse cleanup - shemminger@osdl.org
