[2/2] net/ice: fix VXLAN flow director creation error
Checks
Commit Message
From: Dapeng Yu <dapengx.yu@intel.com>
In original implementation, error returned when creating VXLAN flow
director 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_input_set_hdrs() set ICE_FLOW_SEG_HDR_VXLAN into protocol
header flag of segments of VXLAN FDIR rule, it not necessary, and can
be set automatically by ice_flow_set_fld() later
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.
