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. Invoking a function introduces a small run-time overhead. Sometimes the compiler can minimize this overhead by inlining some of these function calls. In a CPU cache, the "cache size" (or capacity) refers to how much data a cache stores. For instance, a "4 KB cache" is a cache that holds 4 KB of data. The "4 KB" in this example excludes overhead bits such as frame, address, and tag information.
