For monitoring, userspace will try to configure the VIF sdata, while the driver may see the monitor_sdata that is created when only monitor interfaces are up. This causes the odd situation that it may not be possible to store the MU-MIMO configuration on monitor_sdata. Fix this by storing that information on the VIF sdata and updating the monitor_sdata when available and the interface is up. Also, adjust the code that adds monitor_sdata so that it will configure MU-MIMO based on the newly added interface or one of the existing ones. This should give a mostly consistent behaviour when configuring MU-MIMO on sniffer interfaces. Should the user configure MU-MIMO on multiple sniffer interfaces, then mac80211 will simply select one of the configurations. This behaviour should be good enough and avoids breaking user expectations in the common scenarios.

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.
