net/mlx4_en: Add netdev support for TCP/IP offloads of vxlan tunneling
When the device tunneling offloads mode is vxlan do the following
- call SET_PORT with the relevant setting
- add DMFS steering vxlan rule for the device self and multicast mac addresses
of the form: {<ETH, outer-mac> <VXLAN, ANY vnid> <ETH, ANY mac>} --> RSS QP
- set relevant QPC fields in RSS context and RX ring QPs
- in TX flow, set WQE fields to generate HW checksum, and handle gso skbs
which are marked for encapsulation such that the HW will segment them properly.
- in RX flow, read HW offloaded checksum for encapsulated packets from the CQE
- advertize hw_enc_features and NETIF_F_GSO_UDP_TUNNEL to the networking stack
