Packet Forward from RGMII-1 to RGMII-2 on ls1043 with IP address and port modification

[bhargavjayswal]

As per attached screenshot I wanted to send RTP packet from PC1 to PC2 with help of FMC policy.

For POC ,initially I'm only trying to route RGMII-1 UDP packets , where i wanted to change source IPv4 , destination IPv4 , source port and destination port before it goes in to TX frame queue of RGMII-2. 

I have written policy where i am unable to figure out how to change those parameter. Could you please point out how it can be done in attached policy .

Below are debugs

>> cat /sys/class/net/eth2/fqids

Rx error: 331
Rx default: 332
Rx PCD: 14592- 14719
Tx confirmation (mq): 333- 348
Tx error: 349
Tx default confirmation: 350
Tx: 351- 366

>> cat /sys/class/net/eth3/fqids

Rx error: 367
Rx default: 368
Rx PCD: 14720- 14847
Tx confirmation (mq): 369- 384
Tx error: 385
Tx default confirmation: 386
Tx: 387- 402

Note : I am not using DPDK, so please do not drag conversion in that direction, I wanted to route and modified packet from kernel space using DPAA engine and without cpu(core) intervention or process on that packets. .
