By default, after associated to an AP, the wcn36xx bitrate adjustment algorithm starts sending data at 1Mbps, and increases the rate slowly (1Mbps, 2Mbps, 6Mbps...) over the further TX packets. Starting at 1Mbps usually causes the initial throughput to be really low and the maximum possible bitrate to be reached after about hundreed of TX packets. That can be improved by setting a different initial bitrate for data packets via the ENABLE_DYNAMIC_RA_START_RATE configuration value, this value can be a legacy or MCS rate. This patch sets the starting bitrate value to MCS-5, which seems to be a good compromise given it can be quickly adjusted low or up if necessary.

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.
