This is nice, thank you.
In ofp-print.c, it appears that every call to print_port_stat_cond()
passes UINT64_MAX as 'filter' and 1 as 'more'. I think that these
parameters could be omitted. I removed them.
The tree had two different kinds of software network devices that
handled stats different: netdev-vport initializes the counters it
handles to 0 and left the rest as UINT64_MAX, whereas netdev-dummy
zeroed everything it didn't know. Neither one is perfect but the former
seems a little better, so I changed netdev-dummy to work that way too.
I applied this to master, folding in the following incremental.
