So how should Wireshark handle such invalid frames?  As a simple test, I
manually modified an IEEE 802.3 Ethernet packet and changed its length from 38
bytes (with 8 bytes of trailer) to 1501 bytes.  Wireshark displayed it as an
Ethernet II frame of "Type: unknown (0x05dd)" and payload of 46 bytes.  But if
1501-1535 are invalid, maybe at the very least an Expert Info should be added to
report it?
