WebEthernet packets with less than the minimum 64 bytes for an Ethernet packet (header + user data + FCS) are padded to 64 bytes, which means that if there's less than 64-(14+4) = 46 bytes of user data, extra padding data is added to the packet. Beware: the minimum Ethernet packet size is commonly mentioned at 64 bytes, which is including the FCS.
