/*
 *  This setup function configures the Port 0 of Marvell SOHO Switch Device with
 *	capability of PIRL to be :
 *	
 *	1) Ingress Rate    : 128Kbps (128K bit per sec)
 *	2) Discarded frame : Do not account discarded frame due to queue congestion
 *	3) Filtered frame  : Account filtered frame
 *	4) Limit action    : Drop packets when the incoming rate exceeds the limit
 *	5) Rate type       : Rate is based on Traffic type
 *	6) Traffic type    : ARP, MGMT, Multicast, Broadcast, and Unicast frames are 
 *						 tracked as part of the rate resource calculation.
 *	7) Byte counted    : Account only Layer 3 bytes (IP header and payload)
 *
 *	Notes: This sample uses IRL Unit 0. The available number of IRL Units are 
 *	various depending on the device. Please refer to the datasheet for detailed
 *	information.
 *
 *	Notes: Port 0 will be blocked while programming PIRL.
