Subject: [PATCH 0/3] net: core: Unify dstats with tstats and lstats, add
 generic collection helper

The struct pcpu_dstats ("dstats") has a few variations from the other
two stats types (struct pcpu_sw_netstats and struct pcpu_lstats), and
doesn't have generic helpers for collecting the per-cpu stats into a
struct rtnl_link_stats64.

This change unifies dstats with the other types, adds a collection
helper (dev_get_dstats64) for ->ndo_get_stats64, and updates the single
driver (vrf) to use this helper.

Of course, questions/comments/etc are most welcome!
