Yeah, this is a stupid oversight. Adding a fix for this would be fairly
simple. I don't have time to get to it right away but the patch would
be fairly straightforward:
- add xid to ../include/aggregate-stats-in.hh (set in constructor)
- update coreapps/pyrt/pyrt.cc convert_aggregate_stats_in() to add to python
- in coreapps/pyrt/pycontext.cc:
change send stats_request to create a unique xid and return it
reflect this change through send_aggregate_stats_request
I'll add it on the TODO but will happily accept a patch ;-)

Hi all,
Has anyone thought about how to access OpenFlow headers via the Python
API? I am writing a component that collects aggregate statistics from
switches. To pair up the request with the response that generated it,
I need the transaction id field from the OpenFlow headers. (Note that
without a way to do this pairing aggregate statistics are pretty much
useless!) Ideally I would be able to do the following:
xid = send_aggregate_stats_request(...)
def aggregate_stats_handler(xid,dpid,stats):
...
Is something like this is in the works or if there is another way to
achieve the same effect?
Thanks,
Nate
