How is the problem of young Fortinbras solved? What concession has Norway made to quiet young Fortinbras?

The King of Norway rebuked Fortinbras and ordered him to abandon his plan of Danish conquest, which young Fortinbras agreed to do. Overjoyed at his nephew’s acquiescence, Norway then rewarded Fortinbras with a generous annual allowance. Further, Norway granted Fortinbras leave to levy war against the Polish.
