Even if we have a station, we currently call rate_control_send_low() with the NULL station unless further rate control (driver, minstrel) has been initialized. Change this so we can use more information about the station to use a better rate. For example, when we associate with an AP, we will now use the lowest rate it advertised as supported (that we can) rather than the lowest mandatory rate. This aligns our behaviour with most other 802.11 implementations. To make this possible, we need to also ensure that we have non-zero rates at all times, so in case we really have *nothing* pre-fill the supp_rates bitmap with the very lowest mandatory bitmap (11b and 11a on 2.4 and 5 GHz respectively). Additionally, hostapd appears to be giving us an empty supported rates bitmap (it can and should do better, since the STA must have supported for at least the basic rates in the BSS), so ignore any such bitmaps that would actually zero out the supp_rates, and in that case just keep the pre-filled mandatory rates.

README
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.
