This patch adds IPv4 vxlan encap/decap action support to TC-flower offload. For vxlan encap, the driver maintains a tunnel encap hash-table. When a new flow with a tunnel encap action arrives, this table is looked up; if an encap entry exists, it uses the already programmed encap_record_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new encap node is added and the L2 header fields are queried via a route lookup. hwrm_cfa_encap_record_alloc cmd is used to create a new encap record and the encap_record_handle is used as the tunnel_handle while adding the flow. For vxlan decap, the driver maintains a tunnel decap hash-table. When a new flow with a tunnel decap action arrives, this table is looked up; if a decap entry exists, it uses the already programmed decap_filter_handle as the tunnel_handle in the hwrm_cfa_flow_alloc cmd. Else, a new decap node is added and a decap_filter_handle is alloc'd via the hwrm_cfa_decap_filter_alloc cmd. This handle is used as the tunnel_handle while adding the flow. The code to issue the HWRM FW cmds is introduced in a follow-up patch.
