It might be simpler > to just behave as if IPv6 is off when this combination is given. I think we should make it so that the Kconfig rule only allows "m" or "n" for IP_GRE when IPV6=m That's how we handle this kind of situation elsewhere, f.e. see bonding. Eric, please cook up a patch which does this, I think the magic Kconfig dependency formula for this is: depends on IPV6 || IPV6=n Thanks! -- 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
