      net/mlx5: FPGA, Add basic support for Innova · e29341fb
      Ilan Tayari authored
      
      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.
