The socket ends up with EMSGSIZE in it's error queue, so the next time the application does I/O it sees that error immediately from the read/write call and thus knows that path MTU arrived. -- 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
