Message:

reconf: introducing the segment recovery mechanism in the dspin_router

• The p_recovery_cfg port, connected through a signal to a config register in the XICU, is formatted in two fields: the 4 LSb contain the blackhole relative position and the 4 bits after contain the recovery direction.

• A request with the blackhole cluster as destination is rerouted through the defined recovery direction.

• Remove the reconfiguration parameter of the constructor. The p_recovery_cfg port is instantiated when the bind_recovery_port is called. This port is also connected during this function to the signal that is passed as an argument.
