WebProtocol overhead values here are just what they add to the frame. E.g. if you want MTU for QinQ over physical Ethernet links, just add QinQ, as your physical link MTU already takes Ethernet header and first VLAN tag into account. If you want to encapsulate the whole frame into a pseudowire, add Ethernet, VLAN, and QinQ. WebApr 28, 2015 · With an ethernet MTU of 1500, this MSS would be 1460 after subtracting 20 bytes for the IPv4 and TCP header. Specifying an Ethernet "header" of 26 bytes seems to be assuming a Q-in-Q encapsulation. The standard Ethernet header is 14 bytes, with an FCS of 4 bytes at the end of the frame.
