Is there a reason to hardcode 10KB for port 0, and 3KB for the other
ports ? Would there be use cases where the user may want different
It's just that it feels very "hardcoded" to enforce specifically those
Also, does it make sense to mention the CP110 here ? Is this 19 KB
limitation a limit of the PPv2.2 IP, or of the CP110 ?
