5.2. How to use dual ethernet¶
Android dual ethernet had intranet and outer net.
| hardware device name | dts node | Android system device name | Primary and auxiliary |
|---|---|---|---|
| eth0 | gmac1 | Ethernet 2 | Auxiliary network port for intranet |
| eth1 | gmac0 | Ethernet | Primary network port for external network |
5.2.1. IP Addrs¶
get from debug or adb by ifconfig
