I think that the documentation can be improved. What do you think of
this incremental?

- Specifies the number of upcall handler threads that will be created
- by the ofproto-dpif-upcall module. The default value is (number of
- online core - 1).
+ Specifies the number of threads for software datapaths to use for
+ handling new flows. The default is one less than the number of
+ online CPU cores (but at least 1).

<p>
- Note, the n-handler-threads configuration is per datapath and
- not global to the switch. It is best to use only one type of
- datapath.
+ This configuration is per datapath. If you have more than one
+ software datapath (e.g. some <code>system</code> bridges and some
+ <code>netdev</code> bridges), then the total number of threads is
+ <code>n-handler-threads</code> times the number of software
+ datapaths.
