could cause an unsigned length value to be reduced by more than its
value, turning it into a very large value.
I couldn't exactly reproduce bug 6833, but it was due to an attempt to
allocate 4294967110 bytes, and this bug caused remaining_len to equal
4294967110, and it would try to create a reassembled packet tvbuff of
that size, so I'm guessing this fixes 6833.

Specifically: Replace FALSE|0 and TRUE|1 by ENC_BIG_ENDIAN|ENC_LITTLE_ENDIAN as
the encoding parameter for proto_tree_add_item() calls which directly reference
an item in hf[] which has a type of:

FT_UINT24

FT_INT8

keys to have _uint in their names, to match the routines that handle
dissector tables with string keys. (Using _port can confuse people into
thinking they're intended solely for use with TCP/UDP/etc. ports when,
in fact, they work better for things such as Ethernet types, where the
binding of particular values to particular protocols are a lot
stronger.)

This is necessary in case a subdissector had changed it but was unable to
restore it (due to the exception).
Remove check_col().

This enhancement implements dissector for Downstream DOCSIS (Data over Cable)
frames, embedded into MPEG packets and encapsulated into L2TPv3 over IP
(DEPI/D-MPT encapsulation). This type of encapsulation is used in Modular Cable
Modem Termination System (M-CMTS) architecture for head-end components that
comply with DOCSIS.
DEPI, the Downstream External PHY Interface, is the interface between the
M-CMTS Core and the EQAM. More specifically, it is an IP Tunnel between the MAC
and PHY in a Modular CMTS system.
L2TPv3 is described in RFC3931.
DOCSIS DEPI data packet transport mechanism is described CM-SP-DEPI-I03-060728
(Downstream External PHY Interface - CableLabs specification)
The format of MPEG packet carrying DOCSIS data is described in
CM-SP-DRFI-I07-081209 (Data-Over-Cable Service Interface Specifications -
CableLabs specification).

This patch set improves packet loss detection in for MPEG2 Transport Streams
(RFC 2250 / ISO/IEC 13818-1).
1. Improve loss detection by counting skipped TS frames (currently we only
detect a drop). (only store the info globally)
2. Introduce an analysis tree and record/count the info per TS frame.

(1) Trailing/leading spaces are removed from 'name's/'blurb's
(2) Duplicate 'blurb's are replaced with NULL
(3) Empty ("") 'blurb's are replaced with NULL
(4) BASE_NONE, NULL, 0x0 are used for 'display', 'strings' and 'bitmask' fields
for FT_NONE, FT_BYTES, FT_IPv4, FT_IPv6, FT_ABSOLUTE_TIME, FT_RELATIVE_TIME,
FT_PROTOCOL, FT_STRING and FT_STRINGZ field types
(5) Only allow non-zero value for 'display' if 'bitmask' is non-zero

modifiers for 64-bit quantities than the platform's C library does.

The current RTP/MPEG2 Transport Stream dissector has a bug. When both
Adaptation Field and Payload are present in a packet (AFC==3) the
payload is ignored and Wireshark marks the packet as malformed.
This patch to epan/dissectors/packet-mp2t.c fixes the problem.

this patch adds support for MPEG2 transport stream packets in RTP (type
MP2T). It currently dissects the headers of the MPEG2 packets
