ixl: Fix mbuf hash type settings.
IPV6_EXs in RSS never mean fragment. They mean: "- Home address from the home address option in the IPv6 destination options header. If the extension header is not present, use the Source IPv6 Address. - IPv6 address that is contained in the Routing-Header-Type-2 from the associated extension header. If the extension header is not present, use the Destination IPv6 Address." UDP_IPV4_EX is an invalid RSS hash type, which will be removed.
