Add support to request pdev error stats from firmware through HTT stats type 5. This stats type gives information such as list of pdev errors, reasons for reset, logging information about recovery, drain and war stats. etc. Sample output: ------------- echo 5 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats HTT_HW_STATS_PDEV_ERRS_TLV: mac_id = 0 tx_abort = 0 tx_abort_fail_count = 0 rx_abort = 53 .....

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.
