Add support to request transmit DE stats from firmware through HTT stats type 8. These stats give information about enqueued packets, discarded packets, failed packets and other information such as power, bandwidth information, number of retries, etc. Sample output: ------------- echo 8 > /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_TX_DE_CMN_STATS_TLV: mac_id = 0 tcl2fw_entry_count = 0 not_to_fw = 0 .....

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.
