16/* A list of the taps etc. made available by these dissectors:
17 Taps:
18 lbm_stream
19 - A packet is queued for each UIM (unicast immediate message) LBMC message (or fragment)
20 - The data associated with each tap entry is described by lbm_uim_stream_tap_info_t
21 - A single packet may generate multiple tap entries (in the case that a single packet
22 contains multiple LBMC messages)
23 - An LBMC message that spans multiple packets will cause a single entry to be queued,
24 corresponding to the last packet spanned
25 lbm_uim
26 - A packet is queued for each complete (possibly reassembled) UIM message
27 - The data associated with each tap entry is described by lbm_uim_stream_info_t
28 - A single packet may generate multiple tap entries (in the case that a single packet
29 contains multiple complete UIM messages)
30 - An complete UIM message that spans multiple packets will cause a single entry to be queued,
31 corresponding to the last packet spanned
32 lbm_lbmr_topic_advertisement
33 - A packet is queued for each LBMR topic advertisement (TIR)
34 - The data associated with each tap entry is described by lbm_lbmr_topic_advertisement_tap_info_t
35 - A single LBMR message (which may span multiple IP frames, reassembled into a single UDP packet)
36 may generate multiple tap entries (in the case that a single LBMR message contains multiple topic
37 advertisements)
38 lbm_lbmr_topic_query
39 - A packet is queued for each LBMR topic query (TQR)
40 - The data associated with each tap entry is described by lbm_lbmr_topic_query_tap_info_t
41 - A single LBMR message (which may span multiple IP frames, reassembled into a single UDP packet)
42 may generate multiple tap entries (in the case that a single LBMR message contains multiple topic
43 queries)
44 lbm_lbmr_pattern_query
45 - A packet is queued for each LBMR pattern query (TQR specifying a pattern)
46 - The data associated with each tap entry is described by lbm_lbmr_pattern_query_tap_info_t
47 - A single LBMR message (which may span multiple IP frames, reassembled into a single UDP packet)
48 may generate multiple tap entries (in the case that a single LBMR message contains multiple pattern
49 queries)
50 lbm_lbmr_queue_advertisement
51 - A packet is queued for each LBMR queue advertisement (QIR)
52 - The data associated with each tap entry is described by lbm_lbmr_queue_advertisement_tap_info_t
53 - A single LBMR message (which may span multiple IP frames, reassembled into a single UDP packet)
54 may generate multiple tap entries (in the case that a single LBMR message contains multiple queue
55 advertisements)
56 lbm_lbmr_queue_query
57 - A packet is queued for each LBMR queue query (QQR)
58 - The data associated with each tap entry is described by lbm_lbmr_queue_query_tap_info_t
59 - A single LBMR message (which may span multiple IP frames, reassembled into a single UDP packet)
60 may generate multiple tap entries (in the case that a single LBMR message contains multiple queue
61 queries)
62 lbm_lbtrm
63 - A packet is queued for each LBTRM transport message
64 - The data associated with each tap entry is described by lbm_lbtrm_tap_info_t
65 - A single LBTRM transport message (which may span multiple IP frames, reassembled into a single UDP
66 packet) will generate a single tap entry
67 lbm_lbtru
68 - A packet is queued for each LBTRU transport message
69 - The data associated with each tap entry is described by lbm_lbtru_tap_info_t
70 - A single LBTRU transport message (which may span multiple IP frames, reassembled into a single UDP
71 packet) will generate a single tap entry
72 Heuristic subdissector tables:
73 lbm_msg_payload
74 - If the LBMC preference "Use heuristic sub-dissectors" is enabled, the dissector will call any dissector
75 registered in this table via heur_dissector_add(). This allows a customer plugin to dissect the
76 actual payload of their messages.
