Johannes Berg 2182db91e0 nl80211: rework internal_flags usage
Since internal_flags is only 8 bits, we can only have one
more internal flag. However, we can obviously never use all
of possible the combinations, in fact, we only use 14 of
them (including no flags).

Since we want more flags for MLO (multi-link operation) in
the future, refactor the code to use a flags selector, so
wrap all of the .internal_flags assignments in a IFLAGS()
macro which selects the combination according to the pre-
defined list of combinations.

When we need a new combination, we'll have to add it, but
again we will never use all possible combinations.

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.
