Fix missing or incorrect packet types discovered by DTS.
- Non-IP inner packets
  Set the tunnel flag.
- Inner Ethernet packets
  All supported tunnel packets have Ethernet as inner packets. So, set
  INNER_L2_ETHER for all tunnel types.
- IPv4 fragments carrying TCP/UDP
  The NIC indicates TCP/UDP based on the protocol in IP header. For
  fragments, ignore that bit and always set L4_FRAG.
- IPv6 fragments
  The NIC does regconize fragments (IPv6 packets with fragment extension
  headers). Set packet types for these.

Fixes: 93fb21fdbe23 ("net/enic: enable overlay offload for VXLAN and GENEVE")
