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 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: 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: Remove redundant and unneeded messages

2015-08-26T22:07:34Z

The kernel notifies all VXLAN capable registered drivers, i.e. any driver that implements ndo_add_vxlan_port(), of the addition of a port so that the driver can track which ports are in use. There's no need to log this - it just fills the system log with useless and irksome noise. Also, when failing to init SR-IOV interfaces the driver was printing the same message twice. Just remove the inner printk and let the outer message catch enable as well as the other failures.

i40e/i40evf: Add capability to gather VEB per TC stats

2015-08-26T21:56:08Z

This patch adds capability to update per VEB per TC statistics and dump it via ethtool. It also adds a structure to hold VEB per TC statistics. The fields can be filled by reading the GLVEBTC_* counters. Change-ID: I28b4759b9ab6ad5a61f046a1bc9ef6b16fe31538 Signed-off-by: Neerav Parikh Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e: Fix legacy interrupt mode in the driver

2015-08-26T21:51:28Z

This patch fixes the driver flow to take into account legacy interrupts. Over time we added code that assumes MSIX is the only mode that the driver runs in. It also enables a legacy workaround to trigger SWINT when the TX ring has non-cache aligned descriptors pending and interrupts are disabled. We work with a single vector in MSI mode too, so apply the same restrictions as Legacy.

i40e: Move function calls to i40e_shutdown instead of i40e_suspend

i40e: don't degrade __le16

2015-08-26T21:44:38Z

Sparse cries when we compare an __le16 to a u16, almost like it cares about architectures other than x86. Weird. Use the le16_to_cpu macro to make it stop crying. Change-ID: Id068f4d7868a2d3df234a791a76d15938f37db35 Signed-off-by: Mitch Williams Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher
