Have all dissector tables have a "supports Decode As" flag, which defaults to FALSE, and which is set to TRUE if a register_decode_as() refers to it. When adding a dissector to a dissector table with a given key, only add it for Decode As if the dissector table supports it. For non-FT_STRING dissector tables, always check for multiple entries for the same protocol with different dissectors, and report an error if we found them. This means there's no need for the creator of a dissector table to specify whether duplicates of that sort should be allowed - we always do the check when registering something for "Decode As" (in a non-FT_STRING dissector table), and just don't bother registering anything for "Decode As" if the dissector table doesn't support "Decode As", so there's no check done for those dissector tables.

README
Overview:
=========
The dissectors provided by this plugin allow the dissection of DOCSIS 1.1
Frames. Captures of DOCSIS 1.1 frames can be facilitated using Cisco's
Cable Monitor Features found on Cicso UBR7200 and UBR10000 Series Cable Modem
Termination Systems. Captures of DOCSIS 1.1 and DOCSIS 2.0 frames can be
facilitated using the ARRIS Cadant C4 and the ARRIS Cadant C3.
Features:
=========
+ Decode the DOCSIS header + Extended Header. For Data PDU's it will
automatically decode as far up the stack that it can.
+ Decode Mac Management Header. The following Mac Messages
are decoded at present:
REG-REQ
REG-RSP
REG-ACK
RNG-REQ
RNG-RSP
UCC-REQ
UCC-RSP
UCD Messages
MAP Messages
DSA-REQ
DSA-RSP
DSA-ACK
DSC-REQ
DSC-RSP
DSC-ACK
DSD-REQ
DSD-RSP
BPKM-REQ
BPKM-RSP
BPKM Attributes
+ Decode All Appendix C TLV's
+ Decode Concatenated Frames via a recursive call to dissect_docsis()
+ Decode DOCSIS 2.0 packets including:
Type 29 UCD Messages (DOCSIS 2.0 only)
INT-RNG-REQ
