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].

"fastboot" devlink param is used to put the device into fastboot mode
to program firmware to device flash or to obtain device information.
