Documentation: networking: dsa: remove references to switchdev prepare/commit
After the recent series containing commit bae33f2b5afe ("net: switchdev: remove the transaction structure from port attributes"), there aren't prepare/commit transactional phases anymore in most of the switchdev objects/attributes, and as a result, there aren't any in the DSA driver API either. So remove this piece. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
