A method and technique for updating firmware on a multi-protocol network adapter includes: reading parameter values for a firmware update to determine an update scope indicating one or more functions of the network adapter affected by the firmware update and a write scope indicating which of the one or more functions should receive a write request for writing the firmware update to the network adapter. The update tool is operable to: send a message indicating to the one or more functions based on the update scope that a firmware update process is beginning; send a write request to write the firmware update to the one or more functions based on the write scope; send a reset request to reset the one or more functions to activate the firmware update; and send a message indicating to the one or more functions that the firmware update process is completed.
