Ethernet padding value When the data sent in an Ethernet frame is less than 46 bytes, extra padding needs to be added to the payload. The question is: * Which is the value of that Ethernet padding? I'm asking since in real captures I checked this padding seems random, i.e. a changing combination of 1s and 0s.

IEEE 802 packets may have a minimum size restriction. When necessary, the data field should be padded (with octets of zero) to meet the IEEE 802 minimum frame size requirements. This padding is not part of the IP datagram and is not included in the total length field of the IP header.
