    Defines enic_udp_tunnel_add/del for configuring vxlan tunnel offload.
    enic supports offload of only one ipv4/udp port.
    
    There are two modes that fw supports for vxlan offload.
    
    mode 0: fcoe bit is set for encapsulated packet. fcoe_fc_crc_ok is set
    if checksum of csum is ok. This bit is or of ip_csum_ok and
    tcp_udp_csum_ok
    
    mode 2: BIT(0) in rss_hash is set if it is encapsulated packet.
    	BIT(1) is set if outer_ip_csum_ok/
    	BIT(2) is set if outer_tcp_csum_ok
    
    tcp_udp_csum_ok/ipv4_csum_ok is set if inner csum is OK.
