Hi Cong & everyone.

Another rename & some more tweaks.  I'm not sure quite what version
we're up to but on the basis of the name change (again) I'm assuming v1.

Changes:

Changed the netlink parameter passing to mostly indepedent
flags/structures to hopefully facilitate easier future extension of this
action/module.

Sanity checks on userspace passed parameters now return with -EINVAL
instead of silently nulling them out.

RCU'ified the action update based on structure seen in act_csum.  I hope
to $DEITY I've done that right :-)

Closer to perfection?
