Set underlay QPN as part of flow rule when it's applicable. There is one root flow table in the NIC RX namespace and all the underlay QPs steer the traffic to this flow table. In order to prevent QP to get traffic which is not target to its underlay QP, we need to set the underlay QP number as part of the steering matching. Note: When multicast traffic is sent the QPN filtering is done by the firmware as some early step. Adding the QPN match on the flow table entry is wrong as by that time the target QPN holds the multicast address (e.g. FF(s)) and it won't match.

generic api takes care of spreading affinity similar to what mlx5 open coded (and even handles better asymmetric configurations). Ask the generic API to spread affinity for us, and feed him pre_vectors that do not participate in affinity settings (which is an improvement to what we had before). The affinity assignments should match what mlx5 tried to do earlier but now we do not set affinity to async, cmd and pages dedicated vectors. Also, remove mlx5e_get_cpu and introduce mlx5e_get_node (used for allocation purposes) and mlx5_get_vector_affinity (for indirection table construction) as they provide the needed information. Luckily, we have generic helpers to get cpumask and node given a irq vector. mlx5_get_vector_affinity will be used by mlx5_ib in a subsequent patch.

RQs that were configured for "delay drop" will prevent packet drops when their WQEs are depleted. Marking an RQ to be drop-less is done by setting delay_drop_en in RQ context using CREATE_RQ command. Since this feature is globally activated/deactivated by using the SET_DELAY_DROP command on all the marked RQs, we activated/deactivated it according to the number of RQs with 'delay_drop' enabled. When timeout is expired, then the feature is deactivated. Therefore the driver handles the delay drop timeout event and reactivate it.

The Innova FPGA includes shell hardware and Sandbox-Unit (SBU) hardware. The shell hardware is handled by mlx5_core itself, while the SBU is handled by a client driver. Reset the SBU to a well-known initial state when initializing a new device, and set the FPGA to bypass mode when uninitializing a device. This allows the client driver to assume that its device has been reset when a new device is detected. During SBU reset, the FPGA is put into SBU-bypass mode. In this mode packets do not pass through the SBU, so it cannot affect the network data stream at all. A factory-image does not have an SBU, so skip these flows.

Reserved GIDs are entries in the GID table in use by the mlx5_core and its submodules (e.g. FPGA, SRIOV, E-Swtich, netdev). The entries are reserved at the high indexes of the GID table. A mlx5 submodule may reserve a certain amount of GIDs for its own use during the load sequence by calling mlx5_core_reserve_gids, and must also take care to un-reserve these GIDs when it closes. Reservation is only allowed during the load sequence and before any interfaces (e.g. mlx5_ib or mlx5_en) are up. After reservation, a submodule may call mlx5_core_reserved_gid_alloc/ free to allocate entries from the reserved GIDs pool. Reserve a GID table entry for every supported FPGA QP. A later patch in the patchset will remove them from being reported to IB core. Another such patch will make use of these for FPGA QPs in Innova NIC. Added lib/mlx5.h to serve as a library for mlx5 submodlues, and to expose only public mlx5 API, more mlx5 library files will be added in future submissions.

There's no need to free all the SW context since a new fresh kernel will be loaded afterwards. Regarding the FW resources, they should be closed, otherwise we will have leakage in the FW. To accelerate this flow, we execute one command in the beginning that tells the FW that the driver isn't going to close any of the FW resources and asks the FW to clean up everything.

Mellanox Innova is a NIC with ConnectX and an FPGA on the same board. The FPGA is a bump-on-the-wire and thus affects operation of the mlx5_core driver on the ConnectX ASIC. Add basic support for Innova in mlx5_core. This allows using the Innova card as a regular NIC, by detecting the FPGA capability bit, and verifying its load state before initializing ConnectX interfaces. Also detect FPGA fatal runtime failures and enter error state if they ever happen. All new FPGA-related logic is placed in its own subdirectory 'fpga', which may be built by selecting CONFIG_MLX5_FPGA. This prepares for further support of various Innova features in later patchsets.
