It would be good to fix the kstat issues you documented prior to
publicizing the driver interfaces. We should certainly discuss possible
solutions to this in the context of making these interfaces public.
The stat interfaces was never satisfactorily finished off, although
the original Nemo code did allow the driver to set a mask of supported
stats such that Nemo would only create the relevant set.
The idea behind the 'pull a single stat' entry point in the MAC
interface is more to support querying of things like link state or
duplex which tend to be pulled independently of other stats, plus the
efficiency of stat. gathering is really down the to the h/w driver.
Only it knows how much it costs to query the h/w and can easily set up
a shadow area in memory that can be accessed without locks.
It would be nice to have some function that runs to tell the driver when
it should update the shadow area, though.
