For decapsulation, removing a few bytes from head or tail(deps/dpdk/examples/tep_termination/vxlan.c) is faster than copy whole payloads(Moongen/examples/vxlan-example.lua)
This will help packet decapsulation. For example, in Moongen/examples/vxlan-example.lua 'get payload size -> ffi.copy -> setSize' will be simply 'removeLast(headerLen)' Simpler and faster. I changed the name(adj->removeFirst, trim->removeLast) and ignore return type for simplicity.
