The DSA LAG API will be changed to become more similar with the bridge data structures, where struct dsa_bridge holds an unsigned int num, which is generated by DSA and is one-based. We have a similar thing going with the DSA LAG, except that isn't stored anywhere, it is calculated dynamically by dsa_lag_id() by iterating through dst->lags. The idea of encoding an invalid (or not requested) LAG ID as zero for the purpose of simplifying checks in drivers means that the LAG IDs passed by DSA to drivers need to be one-based too. So back-and-forth conversion is needed when indexing the dst->lags array, as well as in drivers which assume a zero-based index.

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.
