[ovs-dev] [PATCH/RFC] ofproto-dpif: Make bonding balance test more robust

It is my observation that when sending 91 packets to a mode=balance
bond interface with three underlying ports in some cases not all ports
receive at least 7 packets. This causes the test to fail.

It may be that failure indicates that the bonding code
needs improvement. But it seems to me that its more likely to
be a valid behaviour.

I have found that by sending 256 packets instead of 91 the test passes
more reliably: I am yet to see it fail.
