On high latency devices (SDIO, USB) ath10k did not do PN replay check, a data frame with an invalid PN number was not discard as it should have been. So this patch implements PN replay in ath10k. PN replay check for fragmented frames is implemented in followup patch. With low latency devices (PCI, AHB) hardware can store the data frames's content to host memory directly and the firmware can fully reorder data frames, and do PN replay check at the same time. But for high latency devices all data frames will be received and stored in firmware's memory and it is hard to do full reorder because of the memory size limitations in the firmware. This is why the PN replay protections needs to be implemented in host driver. Tested on QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.

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.
