| * ixgbe: cleanup reset pathsAlexander Duyck2011-09-16
| | | | | | | | | | | | | | | | | | | | | | The reset paths are overly complicated and are either missing steps or contain extra unnecessary steps such as reading MAC address twice. This change is meant to help clean up the reset paths an get things functioning correctly.

| * ixgbe: Update TXDCTL configuration to correctly handle WTHRESHAlexander Duyck2011-09-16
| | | | | | | | | | | | | | | | | | | | This change updated the TXDCTL configuration. The main goal is to be much more explicit about the configuration and avoid a possible fake TX hang when the interrupt throttle rate is set to 0.

| * ixgbe: combine PCI_VDEVICE and board declaration to same lineAlexander Duyck2011-09-16
| | | | | | | | | | | | | | | | | | | | | | This patch is a minor whitespace cleanup to compress the device ID declaration and board type declaration onto the same line. It seems to make sense since all of the combinations of the two are less than 80 characters and it makes the overall layout a bit more readable.

| * v2 ixgbe: consolidate all MSI-X ring interrupts and poll routines into oneAlexander Duyck2011-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | This change consolidates all of the MSI-X interrupt and polling routines into two single functions. One for the interrupt and one for the code. The main advantage to doing this is that the compiler can optimize the routines into single monolithic functions which should allow all of them function to occupy a single block of memory and as such avoid jumping around.

| * ixgbe: Change default Tx work limit size to 256 buffersAlexander Duyck2011-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes it so that the default Tx work limit is 256 buffers or 1/2 of an entire ring instead of a full ring size so that it is much more likely that we will be able to actually reach the work limit value. Previously with the value set to an entire ring it would not have been possible for us to trigger an event due to the fact that the Tx work is stopped at the point where we cannot place one more buffer on the ring and it is not restarted until cleanup is complete.

* e1000: save skb counts in TX to avoid cache missesDean Nelson2011-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | Virtual Machines with emulated e1000 network adapter running on Parallels' server were seeing kernel panics due to the e1000 driver dereferencing an unexpected NULL pointer retrieved from buffer_info->skb. The problem has been addressed for the e1000e driver, but not for the e1000. Since the two drivers share similar code in the affected area, a port of the following e1000e driver commit solves the issue for the e1000 driver: commit 9ed318d546a29d7a591dbe648fd1a2efe3be1180 Author: Tom Herbert <therbert@google.com> Date: Wed May 5 14:02:27 2010 +0000 e1000e: save skb counts in TX to avoid cache misses In e1000_tx_map, precompute number of segements and bytecounts which are derived from fields in skb; these are stored in buffer_info. When cleaning tx in e1000_clean_tx_irq use the values in the associated buffer_info for statistics counting, this eliminates cache misses on skb fields.
