From: Dmitry Kravkov <dmitry@broadcom.com> Date: Tue, 4 Feb 2014 17:43:03 +0200 > When configuring GRE tunnel using OVS, tcp stream is distributed over > all RSS queues which may cause TCP reordering. It happens since OVS > uses L2GRE protocol when kernel gre uses IPGRE. > Patch defaults gre tunnel to L2GRE which allows proper RSS for L2GRE > packets and (implicitly) disables RSS for IPGRE traffic. > > Signed-off-by: Dmitry Kravkov <dmitry@broadcom.com> > Signed-off-by: Ariel Elior <ariele@broadcom.com> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
