We are using CPU-affinity and packet steering functions in various places in IPFire, but packets might still be received on a random CPU core. This feature enables that packets that belong to the same connection (i.e. have the save tuple) will be steered to the same queue. This will increase cache locality and decrease locking which results in higher throughput. https://www.kernel.org/doc/Documentation/networking/scaling.txt Signed-off-by: Michael Tremer <michael.tremer@ipfire.org> Acked-by: Peter Müller <peter.mueller@ipfire.org> Signed-off-by: Arne Fitzenreiter <arne_f@ipfire.org>
