+	There is really a mess with previous variables, and it seems to me that they are not used

+	The meaning is the following:
+
+	- TotPkts: the amount of packets received by the bpf filter, *before* applying the filter
+	- TotAccepted: the amount of packets that satisfies the filter
+	- TotDrops: the amount of packet that were dropped into the kernel buffer because of lack of space
+	- TotMissed: the amount of packets that were dropped by the physical interface; it is basically 
+	the value of the hardware counter into the card. This number is never put to zero, so this number
+	takes into account the *total* number of interface drops starting from the interface power-on.
+	- OrigMissed: the amount of packets that were dropped by the interface *when the capture begins*.
+	This value is used to detect the number of packets dropped by the interface *during the present
+	capture*, so that (ps_ifdrops= TotMissed - OrigMissed).

+	received (yet) from the client. In this case, (TotAccepted - TotDrops - TotNetDrops) gives a
