This is a good idea.  Thank you.

In ofproto_flow_mod(), the check 
                && !(fm->flags & OFPUTIL_FF_RESET_COUNTS)
can be moved to the top of the function, since it doesn't depend on what
we find in the rule (or whether we find a rule).

This adds a spurious blank line to ofopgroup_complete().
