Folks:
Trying to run the RYU tester.py for OpenFlow 1.3 against an HP 5406zl switch.
Ryu-manager version: 3.23
HP software version: K15.17.007
Got past the control-table number mismatch (HP == 100) ryu-manager test suite
expects 0, and then started to run the suite in earnest.
It appears that there is an error when the tester gets back from the switch an
OFPT_MULTIPART_REPLY OFPMP_FLOW in response to an OFPT_MULTIPART_REQUEST,
OFPMP_FLOW asking for all tables, ports and groups.
Traceback:
- (Ryu internal error.)
Traceback (most recent call last):

The response is consistent with what I see on the HP switch tables.
Anybody have any experience with a similar issue?
