I see your point; the "clone" is handled at translation code, and

I sent out a series based on this, but it appears to reveal a bug in the
clone action that causes segfaults. Try the series without the patch
"XXX Fix segfault in clone action" applied and you should get test
failures in several tests, e.g. 2249 2251 2252 2253 2254 2256 2259 2260
2266 2268 2277 22
Note that there are some differences between kernel datapath and
userspace datapath, when using the SAMPLE action. For userspace, we
execute the nested actions inside SAMPLE inline/immediately, while in
kernel datapath, we defer the nested actions to a fifo queue and
execute in the end.
For exampl

I tested it for a couple of simple cases, it seems ok. But it might

Thanks for working on it!
Can we have nested clone?
actions=clone(push_vlan(1), resubmit(1,2), clone(mod_dl_src:,
output:5) )
BTW, I believe the port 3 will get a 104byte size packet with this action,
right?
actions= clone(truncate(100), push_vlan, output:3)
Thanks

This patch adds OpenFlow clone action with syntax as below:
"clone([action][,action...])". The clone() action makes a copy of the
current packet and executes the list of actions against the packet,
without affecting the packet after the "clone(...)" action. In other
word, the packet before the cl
