ethernet interface config -- android

在 frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetNetworkFactoty.java:

/**
 * Manages connectivity for an Ethernet interface.
 *
 * Ethernet Interfaces may be present at boot time or appear after boot (e.g.,
 * for Ethernet adapters connected over USB). This class currently supports
 * only one interface. When an interface appears on the system (or is present
 * at boot time) this class will start tracking it and bring it up, and will
 * attempt to connect when requested. Any other interfaces that subsequently
 * appear will be ignored until the tracked interface disappears. Only
 * interfaces whose names match the config_ethernet_iface_regex
 * regular expression are tracked.
 *
 * This class reports a static network score of 70 when it is tracking an
 * interface and that interface's link is up, and a score of 0 otherwise.
 *
 * @hide
