IPG not correct #2

The IPG will usually be a bit larger than specified in the python script. This is because the testbench needs some cycles to process the pcap and once it reaches the state where it actually delays, there are already some cycles wasted. This is problematic if you really use this to set the minimum IPG and end up with some extra cycles.

I'm doing a major rewrite work (expand_funcionalities branch) that will deal with that. The file content will be loaded into a memory model at time 0. Probably it will be necessary only one clock cycle to read packet metadata, then start the delay.

Thanks.
