This doesn't seem like such a hot idea. I haven't seen the new
userspace patch, but assuming you're interested in the flags and
not ignoring them in userspace, the user has to specify the hash
seed for rule deletions.
You also have to chose the same seed for all nodes in a cluster.
This seems needlessly complicated, I'd suggest to simply use zero.
