It's only going to paper over this problem, because a window scale of 2 still gets edited by the firewalls yet doesn't cause the kind of damage 7 does.
Also, using a value of 7 is very safe, because it handles even the tinyest of MTU's in use today (512 byte SLIP connections, for example can still advertise sub-MTU sized chunks in the window). Since a window scale of 7 allows a granularity of 128 octets. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
