Just because you cannot stop the events from coming in doesn't mean you can't just queue them up in software or similar. The important bits you get are: 1) RX ring depletion and packet processing all from software interrupt context 2) transparent GRO support, without the generic code having to disclose most of the GRO internals to drivers I think it can be done. I have a similar issue as your's with the Sun virtualized network driver (I can't really stop the hypervisor events from pouring in) on sparc64 and I plan to add NAPI support to it. -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
