Improved tracing for the IP[46] not-enabled case.
now we get
00:00:03:665501: pg-input
...
00:00:03:665681: ethernet-input
...
00:00:03:665691: ip6-input
UDP: 2001::1 -> ffef::1
tos 0x00, flow label 0x0, hop limit 64, payload length 108
UDP: 1234 -> 1234
length 108, checksum 0x7b25
00:00:03:665695: ip6-not-enabled
UDP: 2001::1 -> ffef::1
tos 0x00, flow label 0x0, hop limit 64, payload length 108
UDP: 1234 -> 1234
length 108, checksum 0x7b25
00:00:03:665706: error-drop
ethernet-input: no error
Same goes for IPv4
