This is the only way to avoid the locking in core network (net/core/dev.c) What is deprecated is to assert NETIF_F_LLTX and yet, use a lock in the ndo_xmit() driver method. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
