Ahmad Masri 42fe1e519e wil6210: fix PTK re-key race
Fix a race between cfg80211 add_key call and transmitting of 4/4 EAP
packet. In case the transmit is delayed until after the add key takes
place, message 4/4 will be encrypted with the new key, and the
receiver side (AP) will drop it due to MIC error.

Wil6210 will monitor and look for the transmitted packet 4/4 eap key.
In case add_key takes place before the transmission completed, then
wil6210 will let the FW store the key and wil6210 will notify the FW
to use the PTK key only after 4/4 eap packet transmission was
completed.

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.
