37/* N.B. dissector preferences are taking the place of (some) M-plane parameters, so unfortunately it can be
38 * fiddly to get the preferences into a good state to decode a given capture..
39 * TODO:
40 * - for U-Plane, track back to last C-Plane frame for that eAxC
41 * - use udCompHdr values from C-Plane if not overridden by U-Plane?
42 * N.B. this matching is tricky see 7.8.1 Coupling of C-Plane and U-Plane
43 * - Radio transport layer (eCPRI) fragmentation / reassembly
44 * - Detect/indicate signs of application layer fragmentation?
45 * - Not handling M-plane setting for "little endian byte order" as applied to IQ samples and beam weights
46 * - for section extensions, check more constraints (which other extension types appear with them, order)
47 * - when some section extensions are present, some section header fields are effectively ignored - flag any remaining ("ignored, "shall")?
48 * - re-order items (decl and hf definitions) to match spec order?
