Avoid repeated calls to dsa_to_port() (some hidden behind dsa_is_user_port and some in plain sight) by keeping two struct dsa_port references: one to the port passed as argument, and another to the other ports of the switch that we're iterating over. dsa_to_port(ds, i) gets replaced by other_dp, i gets replaced by other_port which is derived from other_dp->index, dsa_is_user_port is handled by the DSA iterator.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
