vxlan encapsulation sets the udp src port
==
§
Source UDP port – The VXLAN protocol repurposes this standard field in a UDP
packet header. Instead of using this field for the source UDP port, the protocol uses
it as a numeric identifier for the particular flow between VTEPs. The VXLAN
standard does not define how this number is derived, but the source VTEP usually
calculates it from a hash of some combination of fields from the inner Layer 2
packet and the Layer 3 or Layer 4 headers.
