+          Many network cards will drop packets if the packet MTU is larger than the interface MTU.
+          It is common when sniffing network taffic to have encapsulated packets that are larger than the default MTU of 1500.
+          Make sure the MTU of the capture interface is set to at least 1600 or 9216 if you are using jumbo frames.
