This is a router advise packet...

60 00 00 00 00 44 3a ff fe 80 00 00 00 00 00 00 00 12 13 ff fe 14 15
16 ff 02 00 00 00 00 00 00 00 00 00 00 00 00 00 01 86 00 ae 6a 80 00
00 c8 00 05 7e 40 00 00 00 00 03 04 40 c0 ff ff ff ff ff ff ff ff 00
00 00 00 aa aa 00 00 00 00 00 00 00 00 00 00 00 00 00 00 05 01 00 00
00 00 05 00 01 02 02 12 13 ff fe 14 15 16

The checksum doesn't match. When I dig into the packet the error is in
the last field.

01 02 02 12 13 ff fe 14 15 16

That should be

01 01 02 12 13 ff fe 14 15 16

This isn't noise, it happens on every packet. Payload length is 44
instead of 40.

Same packet from the sniffer.....
