Within VST mode, enable modifying the vlan and/or qos for a VF without requiring unbind/rebind. This requires firmware which supports the UPDATE_QP command. (If the command is not available, we fall back to requiring unbind/bind to activate these changes). To avoid race conditions with modify-qp on QPs that are affected by update-qp, this operation is performed on the comm_wq. If the update operation succeeds for all the necessary QPs, a vlan_unregister is performed for the abandoned vlan id.

Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport is considered to be in VST mode. In this mode, the PPF driver configures Ethernet QPs created by this VF to use this vlan id and priority. Currently RoCE isn't supported on that mode. The special values of VID=4095 or VID=0,UP=0 are considered as VGT. Signed-off-by: NRony Efraim <ronye@mellanox.com> Signed-off-by: NOr Gerlitz <ogerlitz@mellanox.com> Signed-off-by: NDavid S.

The different steering modes are global to the device, with DMFS being introduced after SRIOV was merged. Hence, SRIOV guests running legacy / older Linux kernels or non-Linux drivers may provide B0 steering directives when the hypervisor is using DMFS and fail. Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS. Use this fact to enable such legacy guests to run by modifying the SRIOV B0 steering wrapper to translate guest B0 directives to DMFS ones when the device uses DMFS. The translated B0 rule has to be kept in the resource tracker as a B0 object to allow for lookup in case of detach.

Currently, the InfiniBand stack does not support flow steering at the verbs level -- the only usage of flow steering in the IB driver is for L2 multicast attaches. We need to add the IB case to procedure mlx4_QP_FLOW_STEERING_ATTACH_wrapper() to allow IPoIB to work on VFs on ConnectX-3 when flow steering is enabled. Currently, the IB case in mlx4_QP_FLOW_STEERING_ATTACH_wrapper() is missing, so the procedure returns -EINVAL and IPoIB on VFs breaks.

This requires: 1. Replacing the paravirtualized P_Key index (inserted by the guest) with the real P_Key index. 2. For UD QPs, placing the guest's true source GID index in the address path structure mgid field, and setting the ud_force_mgid bit so that the mgid is taken from the QP context and not from the WQE when posting sends. 3. For UC and RC QPs, placing the guest's true source GID index in the address path structure mgid field. 4. For tunnel and proxy QPs, setting the Q_Key value reserved for that proxy/tunnel pair. Since not all the above adjustments occur in all the QP transitions, the QP transitions require separate wrapper functions. Secondly, initialize the P_Key virtualization table to its default values: Master virtualized table is 1-1 with the real P_Key table, guest virtualized table has P_Key index 0 mapped to the real P_Key index 0, and all the other P_Key indices mapped to the reserved (invalid) P_Key at index 127. Finally, add logic in smp_snoop for maintaining the phys_P_Key_cache. and generating events on the master only if a P_Key actually changed.

The driver is modified to support three operation modes. If supported by firmware use the device managed flow steering API, that which we call device managed steering mode. Else, if the firmware supports the B0 steering mode use it, and finally, if none of the above, use the A0 steering mode. When the steering mode is device managed, the code is modified such that L2 based rules set by the mlx4_en driver for Ethernet unicast and multicast, and the IB stack multicast attach calls done through the mlx4_ib driver are all routed to use the device managed API. When attaching rule using device managed flow steering API, the firmware returns a 64 bit registration id, which is to be provided during detach. Currently the firmware is always programmed during HCA initialization to use standard L2 hashing. Future work should be done to allow configuring the flow-steering hash function with common, non proprietary means.

Currently the slave and master resources are deleted after master freed all bitmaps. If any resources were not properly cleaned up during the shutdown process, an Oops would result. Fix so that delete slave (only) resources during cleanup. Master resources are cleaned up during unload process, and need not separately be cleaned. Note that during cleanup, we need to split the resource-tracker freeing functionality. Before removing all the bitmaps, we free any leftover slave resources. However, we can only remove the resource tracker linked list after all bitmap frees, since some of the freeing functions (e.g., mlx4_cleanup_eq_table) use paravirtualized FW commands which expect the resource tracker linked list to be present.
