and unfortunately, it doesn't work. This is what i get when i ping my 720
from an Intel box:

ICMPv6 checksum failed [3ffe:0400:0470:0004:0000:0000:0000:0001 >
ff02:0000:0000:0000:0000:0001:ff00:0002]
NET: 4 messages suppressed.

I'll try to have a look...

Cheers,
Jochen

Excellent - I just don't have more time to look at it.
Obviously, you want to look at the 32-bit version.

Another idea is to compare the generic code output with
the asm return value.

In any case, I'd be happy to commit any patch you come up.

should be fixed now.... pls give it a try. it was not adding proto
correctly.

It's OK now. However, there still seems to be a problem with the socket
interface. From the HP, i can't ping6 anything (no response), although i
can see the packets on the line (with correct checksum) and the reply from
my Intel box (or anything behind it). A ping from Intel to HP works just
fine. Also, i can't even ping6 ::1.

3ffe:400:470:4::2 is the (current) 6bone address of the HP :-)

# ping6 3ffe:400:470:4::2
PING6(56=40+8+8 bytes) 3ffe:400:470:1::dead:fffe --> 3ffe:400:470:4::2
