Siena has a separate SRAM bank for each port. On single-port boards these can be merged together, so each port has an interrupt flag for parity errors in the other port's SRAM. Currently we do not enable such merging and should mask this interrupt source. Signed-off-by:

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:
