Currently, the PMD decides if the software parsing
offload can enable outer IPv4 checksum and tunneled
TSO support by checking config->hw_csum and config->tso
respectively.
This is incorrect, the right way is to check the following
flags returned by the mlx5dv_query_device function:
MLX5DV_SW_PARSING - check general swp support.
MLX5DV_SW_PARSING_CSUM - check swp checksum support.
MLX5DV_SW_PARSING_LSO - check swp LSO/TSO support.
The fix enables the offloads according to the correct
flags returned by the kernel.

mlx5 in Windows needs the software parsing hca capabilities
to query the NIC for TSO and Checksum offloading support.
Added the capability as part of the capabilities
queried by the PMD using DevX.

Query software parsing supported on the NIC.
Save the offloads values in a config parameter.
This is needed for the outer IPv4 checksum and
IP and UPD tunneled packet TSO support.

Currently, the PMD decides if the tunneling offload
can enable VXLAN/GRE/GENEVE tunneled TSO support by checking
config->tunnel_en (single bit) and config->tso.
This is incorrect, the right way is to check the following
flags returned by the mlx5dv_query_device function:
MLX5DV_RAW_PACKET_CAP_TUNNELED_OFFLOAD_VXLAN - if supported the offload
DEV_TX_OFFLOAD_VXLAN_TNL_TSO can be enabled.
MLX5DV_RAW_PACKET_CAP_TUNNELED_OFFLOAD_GRE - if supported the offload
DEV_TX_OFFLOAD_GRE_TNL_TSO can be enabled.
MLX5DV_RAW_PACKET_CAP_TUNNELED_OFFLOAD_GENEVE - if supported the offload
DEV_TX_OFFLOAD_GENEVE_TNL_TSO can be enabled.
The fix enables the offloads according to the correct
flags returned by the kernel.

mlx5 in Windows needs the tunneling hca capabilities
to query the NIC for Inner TSO offloading support.
Added the capability as part of the capabilities
queried by the PMD using DevX.

Query tunneling supported on the NIC.
Save the offloads values in a config parameter.
This is needed for the following TSO support:
DEV_TX_OFFLOAD_VXLAN_TNL_TSO
DEV_TX_OFFLOAD_GRE_TNL_TSO
