ixgbe: initialize interrupt throttle rate

2008-10-09T03:22:48+00:00

commit 15e79f24b60c4b0bf8019423bda4e03a576b02f2 upstream

This commit dropped the setting of the default interrupt throttle rate.

    ixgbe: Introduce MSI-X queue vector code

The following patch adds it back.  Without this the default value of 0
causes the performance of this card to be awful.  Restoring these to the
default values yields much better performance.

This regression has been around since 2.6.25.

ixgbe: remove device ID for unsupported device

2008-08-01T19:43:11+00:00

commit bb5d10ac8cc315d53306963001fe650d88a1cbb2 upstream

The ixgbe driver was untested with device ID 8086:10c8 but still advertises
support.  Currently if this device is present in the system when the driver
is loaded, the system will panic.
Remove this device ID until full support can be tested with available
hardware.  This patch is necessary for 2.6.24, 2.6.25 and 2.6.26

ixgbe: save and restore pcie/msi state to support EEH recovery

2008-04-25T06:07:13+00:00

To enable EEH support for pci-express network adapters, pcie/msi state
needs to be saved and restored for that adapter.

Tested this EEH patch with Intel 10G pci-express ixgbe adapter.

Compilation fix for ixgbe_main.c.

2008-03-29T02:14:53+00:00

Under CONFIG_DCA the compilation is broken since the commit
bd0362dde080cef377d99fa5beb5c25308c29c73 (ixgbe: Add optional
DCA infrastructure).

IXGBE_SUCCESS is not defined anywhere, replace it with 0.

ixgbe: Add optional DCA infrastructure

2008-03-17T11:49:28+00:00

82598 cards and up support DCA, which enables the chipset to warm
up the caches for upcoming payload data. This code makes the
driver plug into the CONFIG_DCA infrastructure that was merged
earlier.

ixgbe: Introduce adaptive interrupt moderation

2008-03-17T11:49:28+00:00

82598 can produce a formidable interrupt rate, and is largely
unusable without some form of moderation. The default behaviour
before this patch is to limit irq's to a reasonable number.
However, just like our other drivers we can reduce latency
for small packet-type traffic considerably by allowing the
irq rate to go up dynamically.

This patch introduces a simple irq moderation algorithm based
on traffic analysis. The driver will use more CPU to service
small packets quicker but will perform the same on bulk traffic
as the old code.

ixgbe: Introduce Multiqueue TX

2008-03-17T11:49:28+00:00

Now that the irq vector code is in place, we can add the conditional
multiqueue TX code in the driver. This requires the optional
CONFIG_NETDEVICES_MULTIQUEUE=y and will not be enabled without
it.
