[asterisk-ss7] performance of libss7 on load

[Matthew Fredrickson]

Well, I'm looking at the code, and what we are trying to do (at least  
if it's an MSU) is request a retransmission of all packets up to that  
number.  When I had written that part, I had used that as a "best  
practice" behavior.   Are you sending it an out of sequence MSU or  
another type of SU?
