SFN8000-series NICs require a new method of setting interrupt moderation, via MCDI. This is indicated by a workaround flag. This new MCDI command takes an explicit time value rather than a number of ticks. It therefore makes sense to also store the moderation values in terms of time, since that is what the ethtool interface is interested in.
