For drivers using software encryption for multicast TX, such as mac80211_hwsim, mac80211 needs to duplicate the multicast frames on each link, if MLO is enabled. Do this, but don't just make it dependent on the key but provide a separate flag for drivers to opt out of this. This is not very efficient, I expect that drivers will do it in firmware/hardware or at least with DMA engine assistence, so this is mostly for hwsim. To make this work, also implement the SNS11 sequence number space that an AP MLD shall have, and modify the API to the __ieee80211_subif_start_xmit() function to always require the link ID bits to be set.

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.
