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 Change-Id: Ia360df39b43281d3a0aa1b686f04b73cfa37c546 Signed-off-by: Neale Ranns <nranns@cisco.com>
