+	// +kubebuilder:validation:Maximum=65535
+	// +optional
+	// +notImplementedHide
+	Port *uint32 `json:"port,omitempty"`


Should use gwapiv1.PortNumber

~~Thanks! Fixed~~

@zhaohuabing I ended up reverting this back to *int32. We only use it in one other place currently vs int32 for 8 other port fields and it breaks the kubebuilder bounds setup.

I'm going to merge this but will ping you on the implementation PR in case you'd still prefer to use PortNumber
