* statistics will not generally add up to the total number of events for
* the device. The @get_base_stats callback allows filling in the delta
* between events for currently live queues and overall device history.
* @get_base_stats can also be used to report any miscellaneous packets
* transferred outside of the main set of queues used by the networking stack.
* When the statistics for the entire device are queried, first @get_base_stats
* is issued to collect the delta, and then a series of per-queue callbacks.
* Only statistics which are set in @get_base_stats will be reported
