-Subject: [PATCH] net: dsa: introduce helpers for iterating through ports using
- dp
-
-Since the DSA conversion from the ds->ports array into the dst->ports
-list, the DSA API has encouraged driver writers, as well as the core
-itself, to write inefficient code.
-
-Currently, code that wants to filter by a specific type of port when
-iterating, like {!unused, user, cpu, dsa}, uses the dsa_is_*_port helper.
-Under the hood, this uses dsa_to_port which iterates again through
-dst->ports. But the driver iterates through the port list already, so
-the complexity is quadratic for the typical case of a single-switch
-tree.
-
-This patch introduces some iteration helpers where the iterator is
-already a struct dsa_port *dp, so that the other variant of the
-filtering functions, dsa_port_is_{unused,user,cpu_dsa}, can be used
-directly on the iterator. This eliminates the second lookup.
-
-These functions can be used both by the core and by drivers.
