Agree. I already tried to do this unconditionally in v2. Folks have raised concerns that it may break some tc modules and in general doesn't work for all types of netdevs that don't set headers_ops. So this flag is the safe compromise. Personally I will be always turning it on. -- 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
