[PATCH v2 net-next 05/10] net: dsa: felix: perform teardown in reverse order of setup

From: Vladimir Oltean <olteanv@gmail.com>

Subsystem: networking drivers, networking [dsa], ocelot ethernet switch driver, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Andrew Lunn, Vladimir Oltean, Vladimir Oltean, Linus Torvalds

From: Vladimir Oltean <vladimir.oltean@nxp.com>

In general it is desirable that cleanup is the reverse process of setup.
In this case I am not seeing any particular issue, but with the
introduction of devlink-sb for felix, a non-obvious decision had to be
made as to where to put its cleanup method. When there's a convention in
place, that decision becomes obvious.
