Patch on iputils to fix broke IPv6 support

that doesnt really explain anything

linux/in6.h from linux-headers should be properly defining those

should but ie headers 2.6.16 define those as
#define IPV6_ADDRFORM           1
#define IPV6_2292PKTINFO        2
#define IPV6_2292HOPOPTS        3
#define IPV6_2292DSTOPTS        4
#define IPV6_2292RTHDR          5
#define IPV6_2292PKTOPTIONS     6
#define IPV6_CHECKSUM           7
#define IPV6_2292HOPLIMIT       8
#define IPV6_NEXTHOP            9
#define IPV6_AUTHHDR            10      /* obsolete */
#define IPV6_FLOWINFO           11

and then iputils fails

then the correct fix is to try and use the new defines and if those dont exist,
fall back to the older ones

should be fixed in cvs now
