But controlling it via a module parameter is one of the worst API choices. Ethtool would be better to use because that is how other network devices control batching. If you do ethtool, you could even extend it to have an number of packets and max latency value. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
