ixgbe: Remove bimodal SR-IOV disabling

2015-09-02T00:17:41Z

When unbinding an SR-IOV device with VFs configured from ixgbe, the driver behaves in one of two ways. If max_vfs was specified, the SR-IOV state is disabled, removing the VFs. The occurs regardless of whether the VF count was later modified through sysfs. If however max_vfs is zero, such as by not specifying the module parameter, the VFs persist after the PF is unbound from ixgbe. If the PF is then bound to vfio-pci to be assigned to a VM, the PF is non-functional. >From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV sysfs callback operation") clearly intended this alternate behavior, but probably didn't realize the PF doesn't work in this mode. This bimodal behavior is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. Remove this behavior so that VFs are removed and the PF is functional for other uses after unbind, regardless of the way VFs are enabled.

ixgbe: Add support for reporting 2.5G link speed

2015-09-02T00:15:20Z

Now that we can do 2.5G link speed, we need to be able to report it. Also change the nested triadic involved in creating the log message to instead use a simpler switch statement to set a string pointer. Signed-off-by: Mark Rustad Signed-off-by: Jeff Kirsher

ixgbe: fix bounds checking in ixgbe_setup_tc for 82598

This patch resolves an issue where users were not able to dynamically set number of queues for 82598 via ethtool -L Reported-by: Tal Abudi Signed-off-by: Emil Tantilov Signed-off-by: Jeff Kirsher

ixgbe: support for ethtool set_rxfh

ixgbe: use kzalloc for allocating one thing

2015-09-02T00:01:17Z

Use kzalloc rather than kcalloc(1.. The semantic patch that makes this change is as follows: // @@ @@ - kcalloc(1, + kzalloc( ...) // and removing checkpatch below CHECK: CHECK: Prefer kzalloc(sizeof(*fwd_adapter)...) over kzalloc(sizeof(struct ixgbe_fwd_adapter)...)

ixgbe: add new bus type for intergrated I/O interface (IOSF)

2015-09-01T23:56:35Z

With this patch we add support for a new bus type ixgbe_bus_type_internal. X550em devices use IOSF and not PCIe bus so this new type is to accommodate them. Signed-off-by: Donald C Skidmore Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher

ixgbe: Add support for entering low power link up state

2015-09-01T23:51:55Z

When the device is closing or suspending, call ixgbe_enter_lplu to enter low power link up state on devices that support it. When this is done, prevent the phy from being reset in the ixgbe_down path so that link is present when calling ixgbe_enter_lplu. Signed-off-by: Don Skidmore Signed-off-by: Jeff Kirsher

ixgbe: Add support for VXLAN RX offloads

Add support for VXLAN RX offloads for the X55x devices that support them. Signed-off-by: Mark Rustad Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher

ixgbe: Add support for UDP-encapsulated tx checksum offload

2015-09-01T23:47:19Z

By using GSO for UDP-encapsulated packets, all ixgbe devices can be directed to generate checksums for the inner headers because the outer UDP checksum can be zero. So point the machinery at the inner headers and have the hardware generate the checksum. Signed-off-by: Mark Rustad Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher
