Hari Chandrakanthan 574fb734ac wifi: mac80211: fix rx link assignment for non-MLO stations
[ Upstream commit cc2b722132 ]

Currently, ieee80211_rx_data_set_sta() does not correctly handle the
case where the interface supports multiple links (MLO), but the station
does not (non-MLO). This can lead to incorrect link assignment or
unexpected warnings when accessing link information.

Hence, add a fix to check if the station lacks valid link support and
use its default link ID for rx->link assignment. If the station
unexpectedly has valid links, fall back to the default link.

This ensures correct link association and prevents potential issues
in mixed MLO/non-MLO environments.

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.
