Implement the IB defined callbacks used to manipulate the policy for the link state, set GUIDs or get statistics information. This functionality is added into a new file that will be used to add any SRIOV related functionality to the mlx5 IB layer. The following callbacks have been added: mlx5_ib_get_vf_config mlx5_ib_set_vf_link_state mlx5_ib_get_vf_stats mlx5_ib_set_vf_guid In addition, publish whether this device is based on a virtual function. In mlx5 supported devices, virtual functions are implemented as vHCAs. vHCAs have their own QP number space so it is possible that two vHCAs will use a QP with the same number at the same time.

Add a vf parameter to mlx5_core_query_vport_counter so we can call it to query counters of virtual functions. Also update current users of the API. PFs may call mlx5_core_query_vport_counter with other_vport set to indicate that they are querying a virtual function. The virtual function to be queried is given by the vf parameter. Virtual function numbering is zero based so the first VF is 0 and so on. When a PF queries its own function, the other_vport parameter is cleared. Signed-off-by:

Add ndo operations to the network driver that enables configuring the following operations: ipoib_set_vf_link_state - configure the VF link policy ipoib_get_vf_config - get link state configuration ipoib_set_vf_guid - set a VF port or node GUID ipoib_get_vf_stats - get statistics of a VF Signed-off-by:

Following the practice exercised for network devices which allow the PF net device to configure attributes of its virtual functions, we introduce the following functions to be used by IPoIB which is the network driver implementation for IB devices. ib_set_vf_link_state - set the policy for a VF link. More below. ib_get_vf_config - read configuration information of a VF ib_get_vf_stats - read VF statistics ib_set_vf_guid - set the node or port GUID of a VF Also add an indication in the device cap flags that indicates that this IB devices is based on a virtual function. A VF shares the physical port with the PF and other VFs. When setting the link state we have three options: 1. Auto - in this mode, the virtual port follows the state of the physical port and becomes active only if the physical port's state is active. In all other cases it remains in a Down state. 2. Down - sets the state of the virtual port to Down 3. Up - causes the virtual port to transition into Initialize state if it was not already in this state. A virtualization aware subnet manager can then bring the state of the port into the Active state. Signed-off-by:

Per the ongoing standardisation process, when virtual HCAs are present in a network, traffic is routed based on a destination GID. In order to access the SA we use the well known SA GID. We also add a GRH required boolean field to the port attributes which is used to report to the verbs consumer whether this port is connected to a virtual network. We use this field to realize whether we need to create an address vector with GRH to access the subnet administrator. We clear the port attributes struct before calling the hardware driver to make sure the default remains that GRH is not required. Signed-off-by:

The subnet prefix is a part of the port_info MAD returned and should be available at the ib_port_attr struct. We define it here and provide a default implementation in case the hardware driver does not provide one. The subnet prefix is required when creating the address vector to access the SA in networks where GRH must be used. Signed-off-by:

Add two new NLAs to support configuration of Infiniband node or port GUIDs. New applications can choose to use this interface to configure GUIDs with iproute2 with commands such as: ip link set dev ib0 vf 0 node_guid 00:02:c9:03:00:21:6e:70 ip link set dev ib0 vf 0 port_guid 00:02:c9:03:00:21:6e:78 A new ndo, ndo_sef_vf_guid is introduced to notify the net device of the request to change the GUID.

Each bypass flow steering priority will be split into two priorities: 1. Priority for don't trap rules. 2. Priority for normal rules. When user creates a flow using IB_FLOW_ATTR_FLAGS_DONT_TRAP flag, the driver creates two flow rules, one used for receiving the traffic and the other one for forwarding the packet to continue matching in lower or equal priorities.

Add support to create flow rule that forward packets to the first flow table in the next priority (next priority could be the first priority in the next namespace or the next priority in the same namespace). This feature could be used for DONT_TRAP rules or rules that only want to mark the packet with flow tag. In order to do it optimally, each flow table has list of all rules that point to this flow table, when a flow table is destroyed/created, we update the list head correspondingly. This kind of rule is created when destination is NULL and action is MLX5_FLOW_CONTEXT_ACTION_FWD_NEXT_PRIO. Signed-off-by:

Allocate proper context for arbitrary scatterlist registration If ib_alloc_mr is called with IB_MR_MAP_ARB_SG, the driver allocate a private klm list instead of a private page list. Set the UMR wqe correctly when posting the fast registration. Also, expose device cap IB_DEVICE_MAP_ARB_SG according to the device id (until we have a FW bit that correctly exposes it).

Devices that are capable in registering SG lists with gaps can now expose it in the core to ULPs using a new device capability IB_DEVICE_SG_GAPS_REG (in a new field device_cap_flags_ex in the device attributes as we ran out of bits), and a new mr_type IB_MR_TYPE_SG_GAPS_REG which allocates a memory region which is capable of handling SG lists with gaps.
