net-sysfs: add support for device-specific rx queue sysfs attributes
Extend existing support for netdevice receive queue sysfs attributes to permit a device-specific attribute group. Initial use case for this support will be to allow the virtio-net device to export per-receive queue mergeable receive buffer size.
