Merge branch 'drivers-net-add-sw_netstats_rx_add-helper'

Fabian Frederick says:

====================
drivers/net: add sw_netstats_rx_add helper

This small patchset creates netstats addition dev_sw_netstats_rx_add()
based on dev_lstats_add() and replaces some open coding
in both drivers/net and net branches.
