This should be a field in reader, not the global packet_buffer, I think.

Also, I did a search of usages of packet_buffer, and there are just a
few of them - it might be worthwhile to eliminate it, and have each
component using it allocate its own buffer. But this can be done in a
separate patch set.

Here too.
