hi!

some protocols are structured in chunks which have the same structure
but differ in content.

examples:

- diameter (avps)
- sigtran suite (parameters)
- sctp (data chunks)

how to access with lua a certain field in such a chunk? NOT necessarly
the first.

for example, using:

local param_len = Field.new("m3ua.parameter_length")

and later on in the tap.packet():

local len = param_len()

will get me only the length of whatever is the first m3ua parameter. how
to get the length of the second, third aso??

thanks a lot!
bye now!
