Wen Gong 33f9747291 ath10k: add fragmentation handler for high latency devices
On high latency devices (SDIO, USB) ath10k did not handle fragmented frames and
all fragmented frames on receive path were lost in ath10k. Even a simple ping
test failed with fragmentation.

The fragmented packets are decapsulated based on the security mode, then the PN
is checked and the fragmented frame is passed to mac80211.  mac80211 in
ieee80211_rx_h_defragment() will then combine the fragment frames and forward
to upper layers.

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.
