Merge patch series "can: export export slcan_ethtool_ops and remove setter functions"

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says:

====================

The c_can, flexcan and slcan use a setter function to populate
net_device::ethtool_ops. Using a setter here add one additional
function call and add some small bloat in the object file. Exporting
the structure allow to remove this setter.

The mcp251xfd uses a similar pattern except that it does some
additional initialization. As such, this driver is left untouched.

* Statistics *

For the slcan driver, this patch reduces the object file by 14 bytes
(details in the first patch). Although we did not conduct a benchmark
for the other drivers but we expect the exact same figures.
