> ICE_FLOW_SEG_HDR_TCP or ICE_FLOW_SEG_HDR_SCTP 2.

> header flag of segments of VXLAN FDIR rule, it not necessary, and can be set

> ICE_FLTR_PTYPE_NONF_IPV4_UDP_VXLAN hides the flow type of inner
> segment of VXLAN FDIR rule, then further causes function:
> ice_fdir_get_gen_prgm_pkt() cannot write correct protocol id into inner
> segment of training packet.

> This patch fixes those defects described above.
