...(or rx_queue_add_kobject) to call sysfs_create_group on the per-netdev attribute group (if non-NULL), adding the attributes in the group to the RX queue kobject. That should allow us to have per-RX queue attributes that are device-specific. I'm not a sysfs expert, but it seems that rx_queue_ktype and rx_queue_sysfs_ops presume that all rx queue sysfs operations are performed on attributes of type rx_queue_attribute. That type will need to be moved from net-sysfs.c to a header file like netdevice.h so that the type can be used in virtio-net when we declare the mergeable_rx_buffer_size attrib...

Hi Jason, Michael Sorry for the delay in response. Jason, I agree this patch ended up being larger than expected. The major implementation parts are: (1) Setup directory structure (driver/per-netdev/rx-queue directories) (2) Network device renames (optional, so debugfs dir has the right name) (3) Support resizing the # of RX queues (optional - we could just export max_queue_pairs files and

The virtio-net device currently uses aligned MTU-sized mergeable receive packet buffers. Network throughput for workloads with large average packet size can be improved by posting larger receive packet buffers. However, due to SKB truesize effects, posting large (e.g, PAGE_SIZE) buffers reduces the throughput of workloads that do not benefit from GRO and have no large inbound packets. This
