+To add IceNIC to your design, add ``HasPeripheryIceNIC`` to your lazy module
+and ``HasPeripheryIceNICModuleImp`` to the module implementation.

+Then add the ``WithIceNIC`` config mixin to your configuration. This mixin

+that the input packet buffer can hold and the ``usePauser`` argument determines
+whether or not the NIC will have a pause handler.
