NF calibration and other elements of long calibration are usually faster than ADCs & I/Q calibrations due to independence of receiption of the OFDM signal. Moreover sometime I/Q calibration can not be completed at all without preceding NF calibration. This is due to AGC, which has a habit to block a weak signal without regular NF calibration. Thus, we do not need to deferr the long calibration forever. So, if the long calibration is requested, then deferr the ADCs & I/Q calibration(s) and run the longcal (the NF calibration in particular) to obtain fresh noise data. Run tested with AR9220.

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.
