I did actually mean seq=2,frag=1, since the seqno assignment happened
after fragmentation in your patch, and after codel reordering, and
would not change the seqno until it encountered a frag=0 packet.

Or maybe that was only with the previous version of the patch.

Yes, fragmented packets are not allowed to be aggregated.
