Merge branch 'net-add-and-use-function-dev_fetch_sw_netstats-for-fetching-pcpu_sw_netstats'
Heiner Kallweit says:
====================
net: add and use function dev_fetch_sw_netstats for fetching pcpu_sw_netstats
In several places the same code is used to populate rtnl_link_stats64
fields with data from pcpu_sw_netstats. Therefore factor out this code
to a new function dev_fetch_sw_netstats().
====================
