This replace the PCI DMA state API (include/linux/pci-dma.h) with the DMA equivalents since the PCI DMA state API will be obsolete. No functional change. For further information about the background: http://marc.info/?l=linux-netdev&m=127037540020276&w=2Signed-off-by:

Due to an errata in 82598 parts MSI-X needs to be disabled in certain ixgbe devices designed to transfer peer-to-peer traffic on the PCIe bus. This patch sets the default interrupt type to MSI rather than MSI-X for specific Cisco ixgbe adapters. Signed-off-by:

The recently introduced bridge mulitcast port group list was only partially using RCU correctly. It was missing rcu_dereference() and missing the necessary barrier on deletion. The code should have used one of the standard list methods (list or hlist) instead of open coding a RCU based link list. Signed-off-by:

This patch adds registers (,tx/rx rings' status and so on) printout code just before resetting adapters. This will be helpful for detecting the root cause of adapters reset. Signed-off-by:

This patch is an alternative to similar patch provided by Joe Perches. Substitute DPRINTK macro for e_<level> that uses netdev_<level> and dev_<level> similar to e1000e. - Convert printk to pr_<level> where applicable. - Use common #define pr_fmt for the driver. - Use dev_<level> for displaying text in parts of the driver where the interface name is not assigned (like e1000_param.c). - Better align test with the new macros.

This reverts commit ff65e827. As explained by Stephen Hemminger, the traversal doesn't require RCU handling as we hold a lock. The list addition et al. calls, on the other hand, do. Signed-off-by:

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. Signed-off-by:

Dimitris Michailidis authored
Some boards' VPDs contain additional keywords or have longer serial numbers, meaning the keyword locations are variable. Ditch the static layout and use the pci_vpd_* family of functions to parse the VPD instead. Signed-off-by:

Current socket backlog limit is not enough to really stop DDOS attacks, because user thread spend many time to process a full backlog each round, and user might crazy spin on socket lock. We should add backlog size and receive_queue size (aka rmem_alloc) to pace writers, and let user run without being slow down too much. Introduce a sk_rcvqueues_full() helper, to avoid taking socket lock in stress situations. Under huge stress from a multiqueue/RPS enabled NIC, a single flow udp receiver can now process ~200.000 pps (instead of ~100 pps before the patch) on a 8 core machine. Signed-off-by:

The way we were setting autoneg via ethtool was inconstant with that of our other drivers. It will change the following: If autoneg is off: >ethtool -a eth0 Pause parameters for eth0: Autonegotiate: off RX: off TX: off Before: >ethtool -A eth0 autoneg on >ethtool -a eth0 Pause parameters for eth0: Autonegotiate: off RX: off TX: off Now: >ethtool -A eth0 autoneg on >ethtool -a eth0 Pause parameters for eth0: Autonegotiate: on RX: on TX: on Signed-off-by:

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(). Signed-off-by:

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. Signed-off-by:
