setup/teardown of COLO proxy module.
we use netlink to communicate with proxy module.
About colo-proxy module:
https://lkml.org/lkml/2015/6/18/32
How to use:

This seems pleasingly self-contained, and to be done in the right
place, but:
I don't understand how discrepant packets are detected, in order to
cause a resync. I mean, I don't see any code in this patch which
receives a notification of a discrepancy and causes a resync. What am
I missing ?
I'm not familar with this part, Wen will answer colo-proxy revelant
questions later.
Thanks

Thanks,
Ian.
