net/mlx5_fpga: Drop INNOVA IPsec support Mellanox INNOVA IPsec cards are EOL in Nov, 2019 [1]. As such, the code is unmaintained, untested and not in-use by any upstream/distro oriented customers. In order to reduce code complexity, drop the kernel code.

RDMA/mlx5: Replace struct mlx5_core_mkey by u32 key In mlx5_core and vdpa there is no use of mlx5_core_mkey members except for the key itself. As preparation for moving mlx5_core_mkey to mlx5_ib, the occurrences of struct mlx5_core_mkey in all modules except for mlx5_ib are replaced by a u32 key.

net/mlx5: Accel, Add TLS tx offload interface Add routines for manipulating TLS TX offload contexts. In Innova TLS, TLS contexts are added or deleted via a command message over the SBU connection. The HW then sends a response message over the same connection. Add implementation for Innova TLS (FPGA-based) hardware. These routines will be used by the TLS offload support in a later patch mlx5/accel is a middle acceleration layer to allow mlx5e and other ULPs to work directly with mlx5_core rather than Innova FPGA or other mlx5 acceleration providers. In the future, when IPSec/TLS or any other acceleration gets integrated into ConnectX chip, mlx5/accel layer will provide the integrated acceleration, rather than the Innova one.

net/mlx5: Accel, Add IPSec acceleration interface Add routines for manipulating the hardware IPSec SA database (SADB). In Innova IPSec, a Security Association (SA) is added or deleted via a command message over the SBU connection. The HW then sends a response message over the same connection. Add implementation for Innova IPSec (FPGA-based) hardware. These routines will be used by the IPSec offload support in a later patch However they may also be used by others such as RDMA and RoCE IPSec. mlx5/accel is a middle acceleration layer to allow mlx5e and other ULPs to work directly with mlx5_core rather than Innova FPGA or other mlx5 acceleration providers. In this patchset we add Innova IPSec support and mlx5/accel delegates IPSec offloads to Innova routines. In the future, when IPSec/TLS or any other acceleration gets integrated into ConnectX chip, mlx5/accel layer will provide the integrated acceleration, rather than the Innova one.

net/mlx5: FPGA, Add high-speed connection routines An FPGA high-speed connection has two endpoints, an FPGA QP and a ConnectX QP. Add library routines to create and connect the endpoints of an FPGA high-speed connection. These routines allow creating and interacting with both types of connections: Shell and Sandbox Unit (SBU). Shell connection provides an interface to the FPGA's address space, which includes the configuration space and the DDR. Use of the shell connection will be introduced in a later patchset. SBU connection provides a command and/or data interface to the application-specific logic within the FPGA. Use of the SBU connection will be introduced in a later patch in this patchset. Some struct definitions are added to a new header file sdk.h, which will be extended in later patches in the patchset. This header file will contain the in-kernel FPGA client driver API.

net/mlx5: Add reserved-gids support 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.

net/mlx5: FPGA, Add basic support for Innova 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. Additional details about hardware architecture will be provided as more features get submitted.
