For packets originating from hardware scan, the channel and band is included in the buffer descriptor (bd->rf_band & bd->rx_ch). For 2Ghz band the channel value is directly reported in the 4-bit rx_ch field. For 5Ghz band, the rx_ch field contains a mapping index (given the 4-bit limitation). The reserved0 value field is also used to extend 4-bit mapping to 5-bit mapping to support more than 16 5Ghz channels. This change adds correct reporting of the frequency/band, that is used in scan mechanism. And is required for 5Ghz hardware scan support.

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.
