2016-09-25i40e: cleanup ATR auto_disable_flags useJacob Keller
Some locations that disable ATR accidentally used the "full" disable by disabling the flag in the standard flags field. This incorrectly forces ATR off permanently instead of temporarily disabling it. In addition, some code locations accidentally set the ATR flag enabled when they only meant to clear the auto_disable_flags. This results in ignoring the user's ethtool private flag settings. Additionally, when disabling ATR via ethtool, we did not perform a flush of the FD table. This results in the previously assigned ATR rules still functioning which was not expected. Cleanup all these areas so that automatic disable uses only the auto_disable_flag. Fix the flush code so that we can trigger a flush even when we've disabled ATR and SB support, as otherwise the flush doesn't work. Fix ethtool setting to actually request a flush. Fix NETIF_F_NTUPLE flag to only clear the auto_disable setting and not enable the full feature.

2016-09-25i40e: add encap csum VF offload flagPreethi Banala
Add ENCAP_CSUM offload negotiation flag. Currently VF assumes checksum offload for encapsulated packets is supported by default. Going forward, this feature needs to be negotiated with PF before advertising to the stack. Hence, we need a flag to control it. This is in regards to prepping up for VF base mode functionality support.

2016-09-25i40e: fix deleting mac filtersAlan Brady
There exists a bug in which deleting a mac filter does not actually occur. The driver reports that the filter has been deleted with no error. The problem occurs because the wrong cmd_flag is passed to the firmware when deleting the filter. The firmware reports an error back to the driver but it is expressly ignored. This fixes the bug by using the correct flag when deleting a filter. Without this patch, deleted filters remain in firmware and function as if they had not been deleted.

This patch fixes the problem where driver shows 100 Mbps as a supported speed, and allows it to be configured for advertising on X722 devices. This patch fixes the problem by not setting the 100 Mbps SGMII flag for X722 devices. Without this patch, the user incorrectly thinks that 100 Mbps is supported and hence might try to advertise it on X722 devices when it is actually not a supported speed.

Emil provides several changes, first simplifies the logic for setting VLAN filtering by checking the VMDQ flag and the old 82598 MAC, instead of having to maintain a list of MAC types. Then made two functions static that are used only within the file, a by-product is sparse is now happy. Added spinlocks to make sure that the MTU configuration is handled properly. Fixed an issue where when SR-IOV is enabled while the ixgbevf driver is loaded would result in all mailbox requests being rejected by ixgbe, so call ixgbe_sriov_reinit() before pci_enable_sriov() to ensure mailbox requests are properly handled. Mark resolves a NULL pointer issue by simply setting the read and write *_ref_mdi pointers for x550em_a devices. Then clearly indicates within ethtool that all MACs support pause frames and made sure that the advertising is set to the requested mode. Fixed an issue where MDIO_PRTAD_NONE was not being used consistently to indicate no PHY address. Alex fixes an issue, where the support for multiple queues when SR-IOV is enabled was added but the support was not reported. With that, fix an issue where the hardware redirection table could support more queues then the PF currently has when SR-IOV is enabled, so use the RSS mask to trim off the bits that are not used. Lastly, instead of limiting the VFs if we do not use 4 queues for RSS in the PF, we can instead just limit the RSS queues used to a power of 2. We can now support use cases where VFs are using more queues than the PF is currently using and can support RSS if so desired. ==================== Signed-off-by: David S.

Sridhar fixes link state event handling by updating the carrier and starts/stops the Tx queues based on the link state notification from PF. Brady fixes an issue where a user defined RSS hash key was not being set because a user defined indirection table is not supplied when changing the hash key, so if an indirection table is not supplied now, then a default one is created and the hash key is correctly set. Also fixed an issue where when NPAR was enabled, we were still using pf->mac_seid to perform the dump port query. Instead, go through the VSI to determine the correct ID to use in either case. Mitch provides one fix where a conditional return code was reversed, so he does a "switheroo" to fix the issue. Carolyn has two fixes, first fixes an issue in the virt channel code, where a return code was not checked for NULL when applicable. Second, fixes an issue where we were byte swapping the port parameter, then byte swapping it again in function execution. Colin Ian King fixes a potential NULL pointer dereference. Bimmy changes up i40evf_up_complete() to be void since it always returns success anyways, which allows cleaning up of code which checked the return code from this function. Alex fixed an issue where the driver was incorrectly assuming that we would always be pulling no more than 1 descriptor from each fragment. So to correct this, we just need to make certain to test all the way to the end of the fragments as it is possible for us to span 2 descriptors in the block before us so we need to guarantee that even the last 6 descriptors have enough data to fill a full frame. v2: dropped patches 1-3, 10 and 12 from the original series since Or Gerlitz pointed out several areas of improvement in the implementation of the VF Port representor netdev.

2016-09-24net/mlx4: Add VF vlan protocol 802.1ad supportMoshe Shemesh
Move the vf to VST 802.1ad mode (mlx4 VST QinQ mode) by setting vf vlan protocol to 802.1ad. VST 802.1ad mode in mlx4, is used for STAG strip/insertion by PF, while the CTAG is set by the VF. Read current vlan protocol as part of the vf configuration state. Upon setting vf vlan protocol to 802.1ad, we use a mechanism of handshake to verify that both the vf and the pf driver version support it. The handshake uses the command QUERY_FUNC_CAP: - The vf sets a pre-defined support bit in input modifier. - A pf that supports the feature sends the request to the vf through a pre-defined field in the output mailbox. - In case vf does not support the feature, the pf will fail the control command (in this case, IP link tool command to set the vf vlan protocol to 802.1ad). No change in VST 802.1Q mode. Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-09-24net: Update API for VF vlan protocol 802.1ad supportMoshe Shemesh
Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

2016-09-23net/mlx5: E-Switch, Support VLAN actions in the offloads modeOr Gerlitz
Many virtualization systems use a policy under which a vlan tag is pushed to packets sent by guests, and popped before the packet is forwarded to the VM. The current generation of the mlx5 HW doesn't fully support that on a per flow level. As such, we are addressing the above common use case with the SRIOV e-Switch abilities to push vlan into packets sent by VFs and pop vlan from packets forwarded to VFs. The HW can match on the correct vlan being present in packets forwarded to VFs (eSwitch steering is done before stripping the tag), so this part is offloaded as is. A common practice for vlans is to avoid both push vlan and pop vlan for inter-host VM/VM (east-west) communication because in this case, push on egress cancels out with pop on ingress. For supporting that, we use a global eswitch vlan pop policy, hence allowing guest A to communicate with both remote VM B and local VM C. This works since the HW pops the vlan only if it exists (e.g for C --> A packets but not for B --> A packets). On the slow path, when a VF vport has an offloaded flow which involves pushing vlans, wheres another flow is not currently offloaded, the packets from the 2nd flow seen by the VF representor on the host have vlan. The VF rep driver removes such vlan before calling into the host networking stack.

2016-09-23i40evf: remove unnecessary error checking against i40e_shutdown_adminqLihong Yang
The i40e_shutdown_adminq function never returns failure. There is no need to check the non-0 return value. Clean up the unnecessary error checking and warning against it.

2016-09-23i40e: Limit TX descriptor count in cases where frag size is greater than 16KAlexander Duyck
The i40e driver was incorrectly assuming that we would always be pulling no more than 1 descriptor from each fragment. It is in fact possible for us to end up with the case where 2 descriptors worth of data may be pulled when a frame is larger than one of the pieces generated when aligning the payload to either 4K or pieces smaller than 16K. To adjust for this we just need to make certain to test all the way to the end of the fragments as it is possible for us to span 2 descriptors in the block before us so we need to guarantee that even the last 6 descriptors have enough data to fill a full frame.

2016-09-23i40evf: remove unnecessary error checking against i40evf_up_completeBimmy Pujari
Function i40evf_up_complete() always returns success. Changed this to a void type and removed the code that checks the return status and prints an error message.
