     I´ve kept the current behavior  and add new options to calculate 
jitter and MOS.
     So, the new options are -R, -P, -J and -M.
     -R will only check for warning and critical for RTA, -P for packet 
loss, -J for jitter and- M for MOS, we can also combine the options, the 
return will reflect the options you chose as will the performance data.
     Again, if you dont use any of the new options, check_icmp should 
behave as it does today.
     We have some customers that just want to check for RTA and packet 
loss, is different services, thus the options -R and -P.

     Bellow some examples, should I sent the patch or just not bother?

     Tks.
