In-band configuration mode
A first state of an interconnect protocol is entered. A particular signal is sent according to the protocol to a device over a link. During the first state, it is detected that a response to the particular signal is received in the first state. It is determined that the device supports a configuration mode outside the protocol based on the received response. The configuration mode is entered based on the response. One or more in-band configuration messages are sent within the configuration mode.
