Hi All,

I want to measure how much time a packet takes inside
a hop. For this I want to measure the time when the
packet enter at an interface and also when it leaves
the other interface.

What is the easiest_and_quickest way to do it.I have
project due for which I need to submit these results.
I tried to run Ethereal at two interfaces, but it
provided me the same time which is at .1ms level so I
could not calculate the processing time inside the
hop.

What can be the way to get better precision?
Is there any way to get this info using skbuff?

Thanks,
Nitin
