The "ocelot" and "seville" tagging protocols populate a bit mask for the
TX ports, so we can use dsa_xmit_port_mask() to centralize the decision
of how to set that field.
This protocol used BIT_ULL() rather than simple BIT() to silence Smatch,
as explained in commit 1f778d500d ("net: mscc: ocelot: avoid type
promotion when calling ocelot_ifh_set_dest"). I would expect that this
tool no longer complains now, when the BIT(dp->index) is hidden inside
the dsa_xmit_port_mask() function, the return value of which is promoted
to u64.

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 reStructuredText 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.
