That's the way one of my employers did it, and I can't think of a better way.

bytes += PPS*overhead

Overhead is likely 20bytes (preamble, SFD, ifg). But it could also be
24B (FCS/CRC might be missing in what otherwise is claimed to be L2).
You may need a lab to confirm what exactly is being counted.

This adjustment could be in DB or it could be render-time, both have
pro and con.
