* Expose EthernetDevice to custom UIsAlistair Delva2020-11-071-20/+1
| | | | | | | | | | | | | | | Make it possible to build a custom UI which uses EthernetRecoveryUI. Since EthernetRecoveryUI must be used with EthernetDevice, but the make_device() function is the only place a custom UI can be specified, we need to move the common EthernetDevice to the recovery_ui core and make a new "default_ethernet_device" which looks like the other default device library stubs, for backwards compatibility. This makes it possible to use EthernetRecoveryUI on cuttlefish. Bug: 172693524 Change-Id: I6a66bb949ef97d06f532adb286d2db4c002d2924
* Add EthernetDevice to manage ethernet connection.Hongguang Chen2020-05-161-0/+136
The current fastbootd only supports USB protocol. But some Android TV devices are built without USB port. The fastbootd cannot be used on those ATV devices due to it. aosp/1295566 enables fastbootd over ethernet. This change adds an EthernetDevice to manage ethernet connection and set fastbootd protcol property fastbootd.protocol to enable fastbootd over ethernet in recovery mode. It uses IPv6 link-local address to not expose the devices out of the network segment. The devices who want to use this EthernetDevice should add “TARGET_RECOVERY_UI_LIB := librecovery_ui_ethernet” into BoardConfig.mk. BUG: 152544169 Test: Enter and exit fastboot mode and check eth0 IPv6 link-local address on screen UI. Change-Id: I73fe44be3790bdba5a6059fbba3f7264b21eed99
