Re: Regarding offloading IPv6 addrconf and ndisc

Hi,

I'm interested in the approach. And I have a couple of comments.
I think DAD and ND are time critical operations.
Can the daemons process with confirming to the specs.
even if it were swapped out?
Can we prevent the oom killer from killing the daemons?

Anyway, we have to consider Pros. and Cons of the approach.

Regards,
