src: Fix test for IPv6 header

Updated:

 src/extra/ipv6.c: Only test the first 4 bits of the putative IPv6 header to be
                   6, since all the other bits are up for grabs.
                   (I have seen nonzero Flow Control on the local interface and
                   RFC2474 & RFC3168 document Traffic Class use).
