net/mlx4: Fix the check in attaching steering rules

2018-04-13T17:50:17Z

[ Upstream commit 6dc06c08bef1c746ff8da33dab677cfbacdcad32 ] Our previous patch (cited below) introduced a regression for RAW Eth QPs. Fix it by checking if the QP number provided by user-space exists, hence allowing steering rules to be added for valid QPs only.

net/mlx4_core: Add support for filtering multicast loopback

2015-10-22T03:16:47Z

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

2015-07-27T22:00:37Z

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

2015-07-27T22:00:37Z

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

2015-04-02T20:25:03Z

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

2015-03-18T18:55:19Z

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.

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

2015-03-02T20:27:19Z

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.

net/mlx4_core: Port aggregation low level interface

2015-02-05T00:14:24Z

Implement the hardware interface required for port aggregation. 1. Disable RX port check on receive - don't perform a validity check that matches to QP's port and the port where the packet is received. 2. Virtual to physical port remap - configure virtual to physical port mapping. Port remap capability for virtual functions. Signed-off-by: Moni Shoua Signed-off-by: Or Gerlitz Signed-off-by: David S.

mlx4: use netdev_rss_key_fill() helper

2014-11-16T20:59:13Z

Use of well known RSS key increases attack surface. Switch to a random one, using generic helper so that all ports share a common key. Also provide ethtool -x support to fetch RSS key Signed-off-by: Eric Dumazet Cc: Amir Vadai Signed-off-by: David S. Miller

net/mlx4: Set vlan stripping policy by the right command

2014-09-10T22:21:34Z

Changing the vlan stripping policy of the QP isn't supported by older firmware versions for the INIT2RTR command. Nevertheless, we've used it. Fix that by doing this policy change using INIT2RTR only if the firmware supports it, otherwise, we call UPDATE_QP command to do the task.
