Add support to request RTT stats from firmware through HTT stats type 65 and 66. HTT stats type 65 support RTT response stats, RTT hardware stats, RTT to-be-read self-generated stats and RTT command-result stats and HTT stats type 66 support RTT initiator stats and RTT hardware stats. These stats give information about number of scheduled commands, responder allocation and termination count, initiator termination count, PASN authentication drop and receive counts, etc. Note: WCN firmware version - WLAN.HMT.1.1.c5-00284.1-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 does not support tags HTT_STATS_PDEV_RTT_RESP_STATS_TAG(194), HTT_STATS_PDEV_RTT_INIT_STATS_TAG(195), HTT_STATS_PDEV_RTT_HW_STATS_TAG(196), HTT_STATS_PDEV_RTT_TBR_SELFGEN_QUEUED_STATS_TAG(197) and HTT_STATS_PDEV_RTT_TBR_CMD_RESULT_STATS_TAG(198), currently.

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 reStructuredText 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.
