* igb: convert igb from using PCI DMA functions to using DMA API functionsAlexander Duyck2010-04-283-58/+61
| | | | | | | | | | | | This patch makes it so that igb now uses the DMA API functions instead of the PCI API functions. To do this the pci_dev pointer that was in the rings has been replaced with a device pointer, and as a result all references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev. This patch is based of of work originally done by Nicholas Nunley.

* ixgbe: ixgbe_down needs to stop dev_watchdogJohn Fastabend2010-04-271-8/+7
| | | | | | | | | | | | | | | | | | | | | There is a small race between when the tx queues are stopped and when netif_carrier_off() is called in ixgbe_down. If the dev_watchdog() timer fires during this time it is possible for a false tx timeout to occur. This patch moves the netif_carrier_off() so that it is called before the tx queues are stopped preventing the dev_watchdog timer from detecting false tx timeouts. The race is seen occosionally when FCoE or DCB settings are being configured or changed. Testing note, running ifconfig up/down will not reproduce this issue because dev_open/dev_close call dev_deactivate() and then dev_activate().

* ixgbe: enable extremely low latencyJesse Brandeburg2010-04-272-9/+87
| | | | | | | | | | | | | | | 82598/82599 can support EITR == 0, which allows for the absolutely lowest latency setting in the hardware. This disables writeback batching and anything else that relies upon a delayed interrupt. This patch enables the feature of "override" when a user sets rx-usecs to zero, the driver will respect that setting over using RSC, and automatically disable RSC. If rx-usecs is used to set the EITR value to 0, then the driver should disable LRO (aka RSC) internally until EITR is set to non-zero again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>, further digging into errata documentation reveals the current enabling or disabling of ASPM L0s and L1 states for certain parts supported by this driver are incorrect. 82571 and 82572 should always disable L1. For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.
