Hi, all: Does anyone know how does the ``rate'''' parameter works in Xen? I know Xen previously use the ``netif'''' data structure, and use the ``credit_bytes'''' and ``remaining credits'''' to do that. But I added printk into thoese functions and they seems to be not called at all. Does Xen change that? I am using Xen 4.0.1. Thanks in advance!
