PMSR (a.k.a. peer measurement) is generalized measurement between two Wi-Fi devices. And currently FTM (a.k.a. fine time measurement or flight time measurement) is the one and only measurement. FTM is measured by RTT (a.k.a. round trip time) of packets between two Wi-Fi devices. Add necessary functionality to allow mac80211_hwsim to be configured with PMSR capability. The capability is mandatory to accept incoming PMSR request because nl80211_pmsr_start() ignores incoming the request without the PMSR capability. In detail, add new mac80211_hwsim attribute HWSIM_ATTR_PMSR_SUPPORT. HWSIM_ATTR_PMSR_SUPPORT is used to set PMSR capability when creating a new radio. To send extra capability details, HWSIM_ATTR_PMSR_SUPPORT can have nested PMSR capability attributes defined in the nl80211.h. Data format is the same as cfg80211_pmsr_capabilities. If HWSIM_ATTR_PMSR_SUPPORT is specified, mac80211_hwsim builds cfg80211_pmsr_capabilities and sets wiphy.pmsr_capa.

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.
