Subject: [PATCH v2 net-next 1/3] net: mscc: ocelot: remove redundant stats_layout pointers
Ever since commit 4d1d157fb6a4 ("net: mscc: ocelot: share the common stat
definitions between all drivers") the stats_layout entry in ocelot and
felix drivers have become redundant. Remove the unnecessary code.
Suggested-by: Vladimir Oltean <olteanv@...il.com>
