app/testpmd: display software packet type

Browse Source 
In addition to the packet type returned by the PMD, also display the
packet type calculated by parsing the packet in software. This is
particularly useful to compare the 2 values.

Note: it does not mean that both hw and sw always have to provide the
same value, since it depends on what hardware supports.
