What kind of v6 traffic are these machines seeing?  I assume they are
endpoints, not routers?  Are they mostly initiating or accepting 
connections over v6?  How many v6 peers do they have?

We discussed this on IRC, and I had an idea of what the fix might be,
but on further reflection that didn't make sense.

I seem to recall that there are several performance problems with IPv6
in Linux 3.2.  It is unlikely to be possible to fix them all with
backported fixes.
