Avraham Stern 422850b29e wifi: iwlwifi: mvm: avoid outdated reorder buffer head_sn
If no frames are received on a queue for a while, the reorder buffer
head_sn may be an old one. When the next frame that is received on
that queue and buffered is a subframe of an AMSDU but not the last
subframe, it will not update the buffer's head_sn. When the frame
release notification arrives, it will not release the buffered frame
because it will look like the notification's NSSN is lower than the
buffer's head_sn (because of a wraparound).
Fix it by updating the head_sn when the first frame is buffered.

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.
