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_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
2. VXLAN VNI offset: 45 is inconsistent with IETF RFC 7348

This patch fixes those defects described above.
