Subject: [PATCH net-next v2 1/4] switchdev: add bridge attributes

From: Scott Feldman <sfeldma@...il.com>

Setting the stage to push bridge-level attributes down to port driver so
hardware can be programmed accordingly.  Bridge-level attribute example is
ageing_time.  This is a per-bridge attribute, not a per-bridge-port attr.
