[ Upstream commit3ff51d7416] Currently, ath11k sends peer assoc command for each peer to firmware when bandwidth changes. Peer assoc command is a bulky command and if many clients are connected, this could lead to firmware buffer getting overflowed leading to a firmware assert. However, during bandwidth change, only phymode and bandwidth also can be updated by WMI set peer param command. This makes the overall command light when compared to peer assoc and for multi-client cases, firmware buffer overflow also does not occur. Remove sending peer assoc command during sta bandwidth change and instead add sending WMI set peer param command for phymode and bandwidth.

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.
