30 * fiddly to get the preferences into a good state to decode a given capture..
31 * TODO:
32 * - tap stats by flow?
33 * - for U-Plane, track back to last C-Plane frame for that eAxC
34 * - use upCompHdr values from C-Plane if not overridden by U-Plane?
35 * N.B. this matching is tricky see 7.8.1 Coupling of C-Plane and U-Plane
36 * - Radio transport layer (eCPRI) fragmentation / reassembly
37 * - Detect/indicate signs of application layer fragmentation?
38 * - Not handling M-plane setting for "little endian byte order" as applied to IQ samples and beam weights
39 * - for section extensions, check more constraints (which other extension types appear with them, order)
40 * - when some section extensions are present, some section header fields are effectively ignored - flag any remaining?
41 * - re-order items (decl and hf definitions) to match spec order
42 * - add hf items to use as roots for remaining subtrees (blurb more useful than filter..)
