Refer to the MTU of your network interface.  (`ifconfig -a`).  For
Ethernet devices, the maximum transmission unit is 1500 bytes.  (1460 data
bytes plus header). Packets can be smaller than that, though, so the
packet count is not directly related to volume of traffic.  There are
columns in that report representing the number of bytes transferred,
though.
