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: Avoid needless PHY access on copper phys

2015-09-02T00:08:18Z

Avoid a needless PHY access on copper phys to save the 10ms wait time for each PHY access. A helper function is introduced to actually do the register access and process the contents. Signed-off-by: Mark Rustad Signed-off-by: Jeff Kirsher

ixgbe: cleanup to use cached mask value

2015-09-02T00:05:59Z

We already cache this FW/SW semaphore mask so might as well use it for consistency. Signed-off-by: Don Skidmore Signed-off-by: Jeff Kirsher

ixgbe: Remove second instance of lan_id variable

2015-09-02T00:03:36Z

This patch removes the redundant lan_id in the phy struct and uses the bus version. Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing. Signed-off-by: Donald C Skidmore Signed-off-by: Jeff Kirsher

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: Remove unused PCI bus types

2015-09-01T23:58:57Z

The ixgbe never has as very doubtfully ever will support either PCI or PCI-X devices. So remove the unused types from the ixgbe_bus_type. Thanks to Alex Duyck for suggesting this. Signed-off-by: Donald C Skidmore Tested-by: Phil Schmitt Signed-off-by: Jeff Kirsher
