Basically I wanted to make the sflow data consistent with netdev
statistics ("ovs-ofctl dump-ports"). In netdev statistics
in case of unknown value there is question mark in output
or the value is left out but there is no logic regarding
the interface type.
In sflow case there will be sent UINT_MAX (unkown counter).
The only risk is that the whole ethernet structure will contain
unkown counters for some interface. So maybe I can add
checking if at least one counter contains known value
and only then send this structure.
What do you think?
