Subject: [PATCH net-next 12/36] can: c_can: export c_can_ethtool_ops and remove c_can_set_ethtool_ops()

From: Vincent Mailhol <mailhol.vincent@...adoo.fr>

The function c_can_set_ethtool_ops() does one thing: populate
net_device::ethtool_ops. Instead, it is possible to directly assign
this field and remove one function call and slightly reduce the object
size. To do so, export c_can_ethtool_ops so it becomes visible to
c_can_main.c.
