I want to see the Ethernet header in tcpdump, but the "-e" does not seem to work
properly. Below is what I get by comparing "tcpdump -x port 520" and "tcpdump -x
-e port 520":
Anyone could advise me any workaround? (I definitely want to see the whole Ether
header because I have my own ETHER_TYPE in my code.)
Thanks a bunch!!

PS: my comparison:
