    Thank you for the correction.  You are right: this is buggy.  OVS does
    not and should not claim to support flow monitoring except as an OVS
    extension.  I knew that the support was not there before, although I
    though we had added it recently, but I did not know that OVS tried
    to support it before.
    Ashish submitted a patch back in January to add full support:
    and we discussed it a bit:
    but I do not know of a v3.
    Ashish, is there a newer version of this patch?
    [Ashish: There was a bug in the related code path which is related to 'usable_protocol' variable not being set and used properly in the existing code.
I will have the v2 patch for this bug this week and then a v3 for the flow monitor as well. The fix for the bug is a pre-requisite for the Flow Monitor v3 patch. Sorry it took so long.] 

    However, for 2.11 and earlier, I expect that the best we can do is to
    simply change this request so that it provokes an error.
