The general equation is:

idleSlopeValue=(AV percentage / 100) x 8192

In this example, dedicating up to 75% of the total bandwidth to the AV traffic:

idleSlopeValue=(75 / 100) x 8192 = 6144

The calculated value for the idleSlopeValue should be written directly to the TX Arbiter Send Slope Control Register. This provides a per-byte increment value when relating this to Legacy Ethernet frame transmission.
