net/mlx4_core: Preparation for VF vlan protocol 802.1ad

2016-09-24T12:01:26+00:00

Check device capability to support VF vlan protocol 802.1ad mode. Add vport attribute vlan protocol. Init vport vlan protocol by default to 802.1Q. Add update QP support for VF vlan protocol 802.1ad. Add func capability vlan_offload_disable to disable all vlan HW acceleration on VF while the VF is set to VF vlan protocol 802.1ad mode. No change in VF vlan protocol 802.1Q (VST) mode.

net/mlx4_en: break out tx_desc write into separate function

2016-07-20T04:46:33+00:00

In preparation for writing the tx descriptor from multiple functions, create a helper for both normal and blueflame access. Signed-off-by: Brenden Blanco Signed-off-by: David S. Miller

IB/mlx4: Support modify_qp for RoCE v2

2016-01-19T20:35:01+00:00

In order to support modify_qp for RoCE v2, we need to set the gid_type in the QP context. Signed-off-by: Moni Shoua Signed-off-by: Matan Barak Signed-off-by: Doug Ledford

net/mlx4_core: Add support for RoCE v2 entropy

2016-01-19T20:35:00+00:00

In RoCE v2 we need to choose a source UDP port, we do so by using entropy over the source and dest QPNs. Signed-off-by: Moni Shoua Signed-off-by: Matan Barak Signed-off-by: Doug Ledford

net/mlx4_core: Add support for filtering multicast loopback

2015-10-22T03:16:47+00:00

Update device capabilities regarding HW filtering multicast loopback support. Add MLX4_UPDATE_QP_ETH_SRC_CHECK_MC_LB attribute to mlx4_update_qp to enable changing QP context to support filtering incoming multicast loopback traffic according the sender's counter index. Set the corresponding bits in QP context to force the loopback source checks if attribute is given and HW supports it.

net/mlx4_en: Add support for hardware accelerated 802.1ad vlan

2015-07-27T22:00:37+00:00

To enable device support in accelerated 802.1ad vlan, the port capability "packet has vlan enable" (phv_en) should be set. Firmware won't work properly, in case phv_en is not set. The user can enable "phv_en" port capability with the new ethtool private flag phv-bit. The phv-bit private flag default value is OFF, users who are interested in 802.1ad hardware acceleration should turn ON the phv-bit private flag: $ ethtool --set-priv-flags eth1 phv-bit on Once the private flag is set, the device is ready for 802.1ad vlan acceleration. The user should also change the interface device features and turn on "tx-vlan-stag-hw-insert" which is off by default: $ ethtool -K eth1 tx-vlan-stag-hw-insert on "phv-bit" private flag setting is available only for Physical Functions(PF), the Virtual Function (VF) will be able to use the feature by setting "tx-vlan-stag-hw-insert" ethtool device feature only if the feature was enabled by the Hypervisor.

net/mlx4: Prepare VLAN macros for 802.1ad Hardware accelerated support

2015-07-27T22:00:37+00:00

To add Hardware accelerated support in 802.1ad vlan, replace Current VLAN macros to CVLAN. Replace: MLX4_WQE_CTRL_INS_VLAN MLX4_CQE_VLAN_PRESENT_MASK With: MLX4_WQE_CTRL_INS_CVLAN MLX4_CQE_CVLAN_PRESENT_MASK Signed-off-by: Hadar Hen Zion Signed-off-by: Amir Vadai Signed-off-by: David S. Miller

net/mlx4: Added qos_vport QP configuration in VST mode

2015-04-02T20:25:03+00:00

Granular QoS per VF feature introduce a new QP field, qos_vport. PF administrator can connect VF QPs to a certain QoS Vport, to inherit its proporties. Connecting QPs to the default QoS Vport (defined as 0) is always allowed, even when there are no allocated VPPs. At this point, only the default vport is connected to QPs.

net/mlx4_core: Add basic support for QP max-rate limiting

2015-03-18T18:55:19+00:00

Add the low-level device commands and definitions used for QP max-rate limiting. This is done through the following elements: - read rate-limit device caps in QUERY_DEV_CAP: number of different rates and the min/max rates in Kbs/Mbs/Gbs units - enhance the QP context struct to contain rate limit units and value - allow to do run time rate-limit setting to QPs through the update-qp firmware command - QP rate-limiting is disallowed for VFs Signed-off-by: Or Gerlitz Signed-off-by: David S. Miller

net/mlx4_core: Fix wrong mask and error flow for the update-qp command

2015-03-02T20:27:19+00:00

The bit mask for currently supported driver features (MLX4_UPDATE_QP_SUPPORTED_ATTRS) of the update-qp command was defined twice (using enum value and pre-processor define directive) and wrong. The return value of the call to mlx4_update_qp() from within the SRIOV resource-tracker was wrongly voided down. Fix both issues. issue: none Fixes: 09e05c3f78e9 ('net/mlx4: Set vlan stripping policy by the right command') Fixes: ce8d9e0d6746 ('net/mlx4_core: Add UPDATE_QP SRIOV wrapper support') Signed-off-by: Matan Barak Signed-off-by: Or Gerlitz Signed-off-by: David S.
