2.6.33-stable review patch. If anyone has any objections, please let us know.

------------------


From: David S. Miller <davem(a)davemloft.net>

[ Upstream commit f935aa9e99d6ec74a50871c120e6b21de7256efb ]

As per RFC 3493 the default multicast hops setting
for a socket should be "1" just like ipv4.

Ironically we have a IPV6_DEFAULT_MCASTHOPS macro
it just wasn't being used.
