I am learning the board LS1021ATSN-PA+ openIL and do not know how to solve the following two problems.
1. There are 6 ethernet ports (Eth0-Eth5) on the board. Eth0 and Eth1 connect the processor, and Eth2-Eth5 connect the switch chip SJA1105TEL. But only Eth2 and Eth3 are available in OpenIL. How can I config and use Eth4 and Eth5?
2. I connect Eth0 and Eth2 with a cable, and then send a flow from Eth0 to Eth2. I found the flow is delivered via the internal port between the process and the switch chip. The cable is unnecessary. How can I send a traffic from Eth0 to Eth2 via a cable?
