It tends to be incredibly helpful to know details like the length of a mac address and what tcp flags mean what if you're looking at an unformatted memory dump.
One example of how this can be handy is when doing low-level NIC bring up, I've read PCIe TLPs from a logic analyzer to correlate them to network traffic.

I bet you spent more than 30 minutes (typical phone screen length) looking at TLPs. Spending 2 minutes to google DLLP/TLP packet structure is not unreasonable.
