Paul reminded me that his XCP system where we see this is running
openvswitch not bridging (all my own tests were with bridging), is this
something which could be caused by vswitch at all? I don't see any
interesting ->frag_list usage in openvswitch.git.

Anyway I'm going to see if I can repro with vswitch.
