From: Dapeng Yu <dapengx...@intel.com>
In original implementation, error returned when creating VXLAN flow rule
with SCTP or TCP as layer 4 protocol of inner segment.
There are several root causes for the error:
1. ice_fdir_input_set_hdrs() set ICE_FLOW_SEG_HDR_UDP into protocol
header flag of inner segment of VXLAN FDIR rule, even if it shall be
ICE_FLOW_SEG_HDR_TCP or ICE_FLOW_SEG_HDR_SCTP
2. ice_fdir_udp4_vxlan_pkt[] is not adapted to the TCP and SCTP protocol.
Its length cannot hold TCP header, only UDP protocol was supported in
original implementation
3. flow type: 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.
Fixes: 855d23a07b36 ("net/ice: support VXLAN VNI field in flow director")
