not present) or decrementing and checking the value of the existent one 


2.Module parameters

None.


3.Exported functions

 - mf_process_maxfwd_header(max_value)
If no Max-Forward header is present in the received request, a header will be
added having the original value equal with "max_value". An OK code is returned

Note that an error code will be also returned if the SIP message couldn't
be parsed or if the Max-Forwrd header's body invalid (non numerical string or
negative numerical value)
