This patch unifies sending control port frames over nl80211 and AF_PACKET sockets a little more. Before this patch, EAPOL frames got QoS prioritization only when using AF_PACKET sockets. __ieee80211_select_queue only selects a QoS-enabled queue for control port frames, when the control port protocol is set correctly on the skb. For the AF_PACKET path this works, but the nl80211 path used ETH_P_802_3. Another check for injected frames in wme.c then prevented the QoS TID to be copied in the frame. In order to fix this, get rid of the frame injection marking for nl80211 ctrl port and set the correct ethernet protocol. Please note: An erlier version of this path tried to prevent frame aggregation for control port frames in order to speed up the initial connection setup a little. This seemed to cause issues on my older Intel dvm-based hardware, and was therefore removed again. Future commits which try to reintroduce this have to check carefully how hw behaves with aggregated and non-aggregated traffic for the same TID.

README
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.
