# HG changeset patch # User kaf24@xxxxxxxxxxxxxxxxxxxx # Node ID addde2d2d97a7a5d399e4f6c41206cb303a7669b # Parent 4b9876fe2f1fbb1996e475e83dc85d843387e353 [NET] front: Zero negotiated bits in xen_set_features When we reconnect to the backend we need to first zero all negotiated bits as the functions xen_set_sg and xen_set_tso do not (and are not supposed to) zero bits when they fail to set them. This patch also permanently enables the NETIF_F_GSO_ROBUST bit as we never parse any GSO fields ourselves (even if we did the backend could not trust us so it's wasted effort).
