I don't know what fastboot is, and reading this doc I see it used in
three forms:
- fastboot protocol
- fastboot mode
- fastboot command & response
The fastboot is sort of a tool. It implements the protocol for
programming the device flash or getting device information. The device
implements the fastboot commands and host issue those commands for
programming the firmware to device flash or to obtain device
information. Inorder to execute those commands, first the device needs
to be put into fastboot mode.
More details on fastboot can be found in links [1].
In the end - I have no idea what the devlink param you're adding does.
"fastboot" devlink param is used to put the device into fastboot mode
to program firmware to device flash or to obtain device information.
