It will allow associating an ethernet interface to a given CPU through RSS by using "ethtool -X ethX weight". Indeed, currently I only enable one entry in the RSS lookup table. Even if it is not really RSS, it allows to get back the irq affinity feature we lost by using the percpu interrupt. The main change compared to the second version is the setup for the XPS instead of using specific hack inside the driver in the forth patch. Th first patch make the default queue associate to each port and no more a global variable. The second patch really associates the RX queues with the CPUs instead of masking the percpu interrupts for doing it. All the RX queues are enabled and are statically associated with the CPUs by using a modulo of the number of present CPUs. But at this stage only one RX queue will receive the stream. The third patch introduces a first level of RSS support through the ethtool functions. As explained in the introduction there is only one entry in the RSS lookup table which permits at the end to associate an mvneta port to a CPU through the RX queues because the mapping is static. ==================== Signed-off-by: David S.
