Currently, rx_duration for each peer is not getting populated in fw_stats debugfs entry for WCN3990. WCN3990 firmware sends rx duration for each peer as part of peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats, firmware expects host to send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD. Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer in fw_stats debugfs entry. Currently the driver handles 32-bit rx_duration, but the rx_duration for WCN3990 can be upto 63 bit. The firmware sends rx_duration split into two 32-bit fields, with the upper 32-bits being valid only if its MSB is set. This change handles the 63-bit rx_duration obtained from WCN3990 and maintain the backward compatibility.

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.
