This series implements the possibility to have a limit on the number of
flows learned by a learn action. After the learn action execution the
pipeline can read the result (to know if the limit was exceeded).
v2->v3:
* When the learned rule expired and there are no packets, instead of
slowpathing the ukey, delete it. This should make the next upcall
a miss upcall and ovs should immediately install a flow. Suggested
by Joe (thanks!).
* NXAST_RAW_LEARN2 is now subtype 45 instead of 44.
v1->v2:
* 'limit' counts both learn flows and flows installed by controller,
suggested by Ben.
* Don't keep a reference to the counter in ukeys
* Squash tests, openflow interface changes and ofproto implementation
into a single commit
* The new cookie-counters module is not used anymore, therefore it's removed
* Fix memory leak in ofproto_flow_mod_learn(): we have to call
ofproto_flow_mod_uninit() if we don't call ofproto_flow_mod_learn_start().
* Simplify ofp-actions changes according to Ben comments(thanks!)
Daniele Di Proietto (3):
ofproto-dpif-xlate: Create XC_LEARN entry after learning.
ofp-actions: Factor out decode_LEARN_{common,spec}().
ofp-actions: Add limit to learn action.
