| /* |
| * 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. |
