[SLUG] Weird IPv6 message

[Peter Chubb <peterc@xxxxxxxxxxxxxxxxxx>]

I'm seeing lots of
     rt6_redirect: source isn't a valid nexthop for redirect target 
messages in my logs.  As far as I can tell from the other machines on
my network, noone is using the machine that's logging as a router; it's
not running radvd; so something weird is happening.

Can anyone hit me with a cluestick?  Googling the message just picks
up the kernel source where it's printed out.  And from my reading of
the source, the message shouldn't be being printed in my environment.
