Sorry to follow up to my own post, but to further clarify, I want to know
the queuing delay experienced by a packet before it is transmitted using
the 802.11 send() function. I tried using ch->timestamp() for each packet
being sent (since it is indicated in the NS Manual that the variable
ts_ can be used for estimating queuing delay) but I was unable to
interpret exactly what this returns.
