Currently, the HTT_H2T_MSG_TYPE_PPDU_STATS_CFG request uses bits 8 to 15 as the bitmask for HTT_PPDU_STATS_CFG_PDEV_ID for firmware PPDU_STATS. However, bit 8 is reserved for SOC stats, and the actual PDEV ID should be encoded using bits 9 to 15. This leads to incorrect PDEV ID encoding in the request, causing it to either ignore the request or apply it to the wrong PDEV. Additionally, pdev_mask calculation is done as pdev_mask = 1 << (i + 1); (i.e. i= num_rxmda_per_pdev) but this is not valid for multiple pdevs(multi-MAC configurations) with 1 rxdma per pdev, as this will mask the same value for all pdevs. To correctly identify each and exact MAC in multi-MAC configurations, the calculation should include ar->pdev_idx: pdev_mask = 1 << i + ar->pdev_idx; Due to these issues, the firmware does not send PPDU_STATS for the intended PDEV, leading to inaccurate and incomplete statistics on the host. This might trigger certain WARN_ON() conditions in host that rely on these statistics. Hence, change the bitmask for HTT_PPDU_STATS_CFG_PDEV_ID as bit 9 to 15 to properly fill the pdev id in request message and change the pdev_mask calculation to consider ar->pdev_idx to mask pdev correctly.

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.
