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 Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.
