LAN 2 Policing Parameters. This register determines the Policing function setting for Ethernet port 2. The Policing
function is used to control the rate at which frames are forwarded to Serial Interfaces. The Policing function can be
configured to send Explicit Back Pressure Flow Control to the Ethernet Sending equipment (Ethernet Pause
Control) or can be used to enable a frame discarding mechanism that restrict the rate at which frame are accepted.
Bit 15: Committed Burst Size Selection (CBSS) This bit function is not available in device revision A1
(GL.IDR.REVn=000).
Bits 10-11: LAN 2 Policing Mode (L2PM[2:1])
Bits 8-9: LAN 2 Policing Credit Range (L2PCR[2:1])
Bits 0-7: LAN 2 Policing Credit Threshold (L2PCT[8:1]). This register specifies the Credit Threshold setting of
the Policing function. Only values between 8 to 255 are supported.
