fuzzing.c:314:45: error: ‘ETHERTYPE_IPV6’ undeclared (first use in this function); did you mean ‘ETHERTYPE_IP6’?
  314 |                                 (l2proto == ETHERTYPE_IPV6) ? l4data : NULL);
      |                                             ^~~~~~~~~~~~~~
      |                                             ETHERTYPE_IP6

To be honest, I haven't checked yet the differences in that architecture - possibly indeed just using ETHERTYPE_IP6 was enough to fix this. From browsing the sources it seems this should be done anyway already for consistency reasons.

I'll investigate Monday. If I find something I should have time In Tuesday to work on it.
