In AP (and IBSS) mode, we can only set GTKs to firmware after we have sent down the multicast station, but this we can only do after we've enabled beaconing, etc. However, during rfkill exit, hostapd will configure the keys before starting the AP, and cfg80211/mac80211 accept it happily. On earlier devices, this didn't bother us as GTK TX wasn't really handled in firmware, we just put the key material into the TX cmd and thus it only mattered when we actually transmitted a frame. On newer devices, however, the firmware needs to track all of this and that doesn't work if we add the key before the (multicast) sta it belongs to. To fix this, keep a list of keys to add during AP enable, and call the function there.

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.
