Extend the devlink health reporter registered by mlxsw to report new health events and their related parameters. These are meant to aid in debugging of hardware / firmware issues. Beside the test event ('MLXSW_REG_MFDE_EVENT_ID_TEST') that is triggered following the devlink health 'test' sub-command, the new events are used to report the triggering of asserts in firmware code ('MLXSW_REG_MFDE_EVENT_ID_FW_ASSERT') and hardware issues ('MLXSW_REG_MFDE_EVENT_ID_FATAL_CAUSE'). Each event is accompanied with a severity parameter and per-event parameters that are meant to help root cause the detected issue. Signed-off-by:Danielle Ratson <danieller@nvidia.com> Signed-off-by:

Commit 0a6890b9 ("bnx2x: Utilize FW 7.13.15.0.") added validation for fastpath HSI versions for different client init which was not meant for SR-IOV VF clients, which resulted in firmware asserts when running VF clients with different fastpath HSI version. This patch along with the new firmware support in patch #1 fixes this behavior in order to not validate fastpath HSI version for the VFs. Fixes: 0a6890b9 ("bnx2x: Utilize FW 7.13.15.0.")

Simon Horman says: ==================== allow user to offload tc action to net device Baowen Zheng says: Allow use of flow_indr_dev_register/flow_indr_dev_setup_offload to offload tc actions independent of flows. The motivation for this work is to prepare for using TC police action instances to provide hardware offload of OVS metering feature - which calls for policers that may be used by multiple flows and whose lifecycle is independent of any flows that use them. This patch includes basic changes to offload drivers to return EOPNOTSUPP if this feature is used - it is not yet supported by any driver.

The MPTCP packet scheduler has sub-optimal behavior with asymmetric subflows: if the faster subflow-level cwin is closed, the packet scheduler can enqueue "too much" data on a slower subflow. When all the data on the faster subflow is acked, if the mptcp-level cwin is closed, and link utilization becomes suboptimal. The solution is implementing blest-like[1] HoL-blocking estimation, transmitting only on the subflow with the shorter estimated time to flush the queued memory. If such subflows cwin is closed, we wait even if other subflows are available. This is quite simpler than the original blest implementation, as we leverage the pacing rate provided by the TCP socket. To get a more accurate estimation for the subflow linger-time, we maintain a per-subflow weighted average of such info. Additionally drop magic numbers usage in favor of newly defined macros and use more meaningful names for status variable.

For VIRTCHNL_VF_OFFLOAD_VLAN, PF's would limit the number of VLAN filters a VF was allowed to add. However, by the time the opcode failed, the VLAN netdev had already been added. VIRTCHNL_VF_OFFLOAD_VLAN_V2 added the ability for a PF to tell the VF how many VLAN filters it's allowed to add. Make changes to support that functionality. Signed-off-by:

The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability added support that allows the VF to support 802.1Q and 802.1ad VLAN insertion and stripping if successfully negotiated via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS. Multiple changes were needed to support this new functionality. 1. Added new aq_required flags to support any kind of VLAN stripping and insertion offload requests via virtchnl. 2. Added the new method iavf_set_vlan_offload_features() that's used during VF initialization, VF reset, and iavf_set_features() to set the aq_required bits based on the current VLAN offload configuration of the VF's netdev. 3. Added virtchnl handling for VIRTCHNL_OP_ENABLE_STRIPPING_V2, VIRTCHNL_OP_DISABLE_STRIPPING_V2, VIRTCHNL_OP_ENABLE_INSERTION_V2, and VIRTCHNL_OP_ENABLE_INSERTION_V2. Signed-off-by:

The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability added support that allows the PF to set the location of the Tx and Rx VLAN tag for insertion and stripping offloads. In order to support this functionality a few changes are needed. 1. Add a new method to cache the VLAN tag location based on negotiated capabilities for the Tx and Rx ring flags. This needs to be called in the initialization and reset paths. 2. Refactor the transmit hotpath to account for the new Tx ring flags. When IAVF_TXR_FLAGS_VLAN_LOC_L2TAG2 is set, then the driver needs to insert the VLAN tag in the L2TAG2 field of the transmit descriptor. When the IAVF_TXRX_FLAGS_VLAN_LOC_L2TAG1 is set, then the driver needs to use the l2tag1 field of the data descriptor (same behavior as before). 3. Refactor the iavf_tx_prepare_vlan_flags() function to simplify transmit hardware VLAN offload functionality by only depending on the skb_vlan_tag_present() function. This can be done because the OS won't request transmit offload for a VLAN unless the driver told the OS it's supported and enabled. 4. Refactor the receive hotpath to account for the new Rx ring flags and VLAN ethertypes. This requires checking the Rx ring flags and descriptor status bits to determine the location of the VLAN tag. Also, since only a single ethertype can be supported at a time, check the enabled netdev features before specifying a VLAN ethertype in __vlan_hwaccel_put_tag(). Signed-off-by:

Based on VIRTCHNL_VF_OFFLOAD_VLAN_V2, the VF can now support more VLAN capabilities (i.e. 802.1AD offloads and filtering). In order to communicate these capabilities to the netdev layer, the VF needs to parse its VLAN capabilities based on whether it was able to negotiation VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2 or neither of these. In order to support this, add the following functionality: iavf_get_netdev_vlan_hw_features() - This is used to determine the VLAN features that the underlying hardware supports and that can be toggled off/on based on the negotiated capabiltiies. For example, if VIRTCHNL_VF_OFFLOAD_VLAN_V2 was negotiated, then any capability marked with VIRTCHNL_VLAN_TOGGLE can be toggled on/off by the VF. If VIRTCHNL_VF_OFFLOAD_VLAN was negotiated, then only VLAN insertion and/or stripping can be toggled on/off. iavf_get_netdev_vlan_features() - This is used to determine the VLAN features that the underlying hardware supports and that should be enabled by default. For example, if VIRTHCNL_VF_OFFLOAD_VLAN_V2 was negotiated, then any supported capability that has its ethertype_init filed set should be enabled by default. If VIRTCHNL_VF_OFFLOAD_VLAN was negotiated, then filtering, stripping, and insertion should be enabled by default. Also, refactor iavf_fix_features() to take into account the new capabilities. To do this, query all the supported features (enabled by default and toggleable) and make sure the requested change is supported. If VIRTCHNL_VF_OFFLOAD_VLAN_V2 is successfully negotiated, there is no need to check VIRTCHNL_VLAN_TOGGLE here because the driver already told the netdev layer which features can be toggled via netdev->hw_features during iavf_process_config(), so only those features will be requested to change.

In order to support the new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability the VF driver needs to rework it's initialization state machine and reset flow. This has to be done because successful negotiation of VIRTCHNL_VF_OFFLOAD_VLAN_V2 requires the VF driver to perform a second capability request via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS before configuring the adapter and its netdev. Add the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit when sending the VIRTHCNL_OP_GET_VF_RESOURECES message. The underlying PF will either support VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2 or neither. Both of these offloads should never be supported together. Based on this, add 2 new states to the initialization state machine: __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS __IAVF_INIT_CONFIG_ADAPTER The __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state is used to request/store the new VLAN capabilities if and only if VIRTCHNL_VLAN_OFFLOAD_VLAN_V2 was successfully negotiated in the __IAVF_INIT_GET_RESOURCES state. The __IAVF_INIT_CONFIG_ADAPTER state is used to configure the adapter/netdev after the resource requests have finished. The VF will move into this state regardless of whether it successfully negotiated VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2. Also, add a the new flag IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS and set it during VF reset. If VIRTCHNL_VF_OFFLOAD_VLAN_V2 was successfully negotiated then the VF will request its VLAN capabilities via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS during the reset. This is needed because the PF may change/modify the VF's configuration during VF reset (i.e. modifying the VF's port VLAN configuration). This also, required the VF to call netdev_update_features() since its VLAN features may change during VF reset. Make sure to call this under rtnl_lock(). Signed-off-by:

Currently VIRTCHNL only allows for VLAN filtering and offloads to happen on a single 802.1Q VLAN. Add support to filter and offload on inner, outer, and/or inner + outer VLANs. This is done by introducing the new capability VIRTCHNL_VF_OFFLOAD_VLAN_V2. The flow to negotiate this new capability is shown below. 1. VF - sets the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit in the virtchnl_vf_resource.vf_caps_flags during the VIRTCHNL_OP_GET_VF_RESOURCES request message. The VF should also set the VIRTCHNL_VF_OFFLOAD_VLAN bit in case the PF driver doesn't support the new capability. 2. PF - sets the VLAN capability bit it supports in the VIRTCHNL_OP_GET_VF_RESOURCES response message. This will either be VIRTCHNL_VF_OFFLOAD_VLAN_V2, VIRTCHNL_VF_OFFLOAD_VLAN, or none. 3. VF - If the VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability was ACK'd by the PF, then the VF needs to request the VLAN capabilities of the PF/Device by issuing a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS request. If the VIRTCHNL_VF_OFFLOAD_VLAN capability was ACK'd then the VF knows only single 802.1Q VLAN filtering/offloads are supported. If no VLAN capability is ACK'd then the PF/Device doesn't support hardware VLAN filtering/offloads for this VF. 4. PF - Populates the virtchnl_vlan_caps structure based on what it allows/supports for that VF and sends that response via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS. After VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS is successfully negotiated the VF driver needs to interpret the capabilities supported by the underlying PF/Device. The VF will be allowed to filter/offload the inner 802.1Q, outer (various ethertype), inner 802.1Q + outer (various ethertypes), or none based on which fields are set. The VF will also need to interpret where the VLAN tag should be inserted and/or stripped based on the negotiated capabilities. Signed-off-by:
