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