i40e: fix annoying message

2015-10-23T01:06:18Z

The driver was printing a message about not being able to assign VMDq because of a lack of MSI-X vectors. This was because a line was missing that initialized a variable, simply a merge error. Signed-off-by: Jesse Brandeburg Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e: fix stats offsets

2015-10-23T00:48:21Z

The code was setting up stats that were not being initialized. This caused several counters to be displayed incorrectly, due to indexing beyond the array of strings when printing stats. Signed-off-by: Jesse Brandeburg Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e/i40evf: set AQ count after memory allocation

2015-10-07T11:13:50Z

The standard way to check if the AQ is enabled is to look at the count field. So we should only set this field after we have successfully allocated memory. To do otherwise is to incite panic among the populace. Signed-off-by: Mitch Williams Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

i40e: fix offload of GRE tunnels

2015-10-05T11:31:41Z

The driver still was not offloading TSO on GRE tunnels because it forgot to set the GSO_GRE flag, causing lots of retransmits. This fixes generic GRE traffic (like a tunnel added like below) whereas before it would get 1Gb/s or less, now on a 10G adapter it gets 8.7Gb/s. ip ad ad 11.1.0.2/24 dev ens2f0 ip l set ens2f0 up ip link add gre2 type gretap remote 11.1.0.1 local 11.1.0.2 dev ens2f0 ip l set gre2 up ip ad ad 192.168.124.2/24 dev gre2 ping 192.168.124.1 netperf -H 192.168.124.1 Signed-off-by: Jesse Brandeburg Signed-off-by: Jeff Kirsher Signed-off-by: David S.

i40e/i40evf: check for stopped admin queue

2015-09-29T03:57:14Z

It's possible that while we are waiting for the spinlock, another entity (that owns the spinlock) has shut down the admin queue. If we then attempt to use the queue, we will panic. Add a check for this condition on the receive side. This matches an existing check on the send queue side.

i40e: fix VLAN inside VXLAN

2015-09-29T03:56:58Z

Previously to this patch, the hardware was removing VLAN tags from the inner header of VXLAN packets. The hardware configuration can be changed to leave the packet alone since that is what the linux stack expects for this type of VLAN in VXLAN packet.

ixgbe: Resolve "initialized field overwritten" warnings

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
