* For the size of the user data, refer to the following section.
Size of the user data
The size of the user data is calculated from the maximum frame size (gross 548 bytes) minus
the following values: 1 for the CP itself, 1 per Interface, 1 per port, 1 for each plugged-in
module in HW Config or per slot used.
