net/mlx4_core: Add basic support for TCP/IP offloads under tunneling
Add the low-level device commands and definitions used for TCP/IP HW offloads
of tunneled/vxlan traffic which are supported by the ConnectX3-pro NIC.
This is done through the following elements:
- read tunneling device caps in QUERY_DEV_CAP
- add helper function to do SET_PORT for tunneling
- add DMFS VXLAN steering rule definitions
- add CQE and WQE checksum offload field definitions
