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.

i40e: Set defport behavior for the Main VSI when in promiscuous mode

2015-09-01T23:33:00Z

This fixes bugs where the port is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a SW bridge is created on top of the device. This also fixes issues where the promiscuous behavior setting was not being preserved across a reset caused by features being enabled or disabled. We are using defport instead of doing a true promiscuous mode because we do not need to receive the SRIOV or VMDq VSI directed traffic which would suck up bandwidth and is really not intended for the SW bridge. In addition, with defport we get VLAN promiscuous behavior which is not possible from the VSI level promiscuous setting.

i40e/i40evf: Cache the CEE TLV status returned from firmware

2015-08-26T22:12:16Z

Store the CEE TLV status returned by firmware to allow drivers to dump that for debug purposes. Change-ID: Ie3c4cf8cebabee4f15e1e3fdc4fc8a68bbca40ee Signed-off-by: Neerav Parikh Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e/i40evf: add VIRTCHNL_VF_OFFLOAD flag

2015-08-26T22:09:54Z
