This is an update for the DCCP dissector and has previously been sent to
the DCCP dissector maintainer, Francesco Fondelli, (CC:ed), who supplied
the Acked-by.
I have been using it with profit for several weeks.

This patch provides the following extensions:
 * type-dependent decoding of feature-negotiation options (NN and SP types of
options,
  NN is a 1..6 byte value in network-byte-order, SP is always a list of
unsigned char)
 * decoding for CCID3 Send Loss Event Rate feature
 * some pretty-printing of options

 * decoding of CCID3-specific options
       - Loss Event Rate (receiver report)
       - Receive Rate (also reported by receiver)

 * there was a change in the spec - the NDP count at sometime `grew' from 3 to
6 bytes
  (it was the same in the kernel). I have updated the data type from uint32 to
uint64

 * utility function to decode from network-byte-order into host byte order with
variable length
