Hi Ben, Hi All,
this series adds infrastructure and message encoding and decoding
to allow Open Flow 1.2 to be used to the extent that ovs-controller
works as a learning-switch and similar logic implemented using Ryu[1].
[1] Ryu is an OpenFlow controller implemented in Python
http://osrg.github.com/ryu/
Differing from the previous posting, this series also supports a number of
statistics messages. These have been tested using the dump-flows,
dump-aggregate, dump-port and dump-tables subcommands of ovs-ofctl.
This series also includes a number of ofp-print.at tests which were
not present in the previous series.
Finally, it also addresses all concerns raised by Ben in relation to
the previous posting.
I believe this series is ready for review.
Base
----
This series is based the of1.1 branch of git://benpfaff.org/openvswitch,
commit bce80ff228223ec9dfde8d348822e264cf99487e (ofp-util: Work on decoding
OF1.1 flow_mods.).
Availability
------------
This series is availabile in the devel/of1.2 (n.b: not devel/of12) branch
of git://github.com/horms/openvswitch.git

The last three patches are local hacks I have been using. They should not
be applied but are provided for reference, in particular for anyone who
wishes to try learning-switch testing. These patches should not be applied.
[PATCH 43/45] Local: learning-switch: Call ofputil_encode_flow_mod()
[PATCH 44/45] Local: ovs-controller: Make sure vconn is connected
[PATCH 45/45] Local: Allow Open Flow 1.2 session to be negotiated
