Normally I don't advise modifying the supplied code. However, because you just
want to simulate packet loss for testing (i.e., I presume you don't plan on
building a product that loses packets :-), you might as well just modify the
(#ifdef'd out) code that's already there.
E.g., if you want to simulate N% packet loss (where N is an integer in the
range [0,100], then you could change the "if" condition above to
if ((our_random()%100 >= N) // simulate N% packet loss
