The mac80211_hwsim driver does not specify supported cipher types, which in turn enables all ciphers to be supported in software. (see net/mac80211/main.c:ieee80211_init_cipher_suites). Allowing ciphers to be configurable is valuable for simulating older drivers that may not support all ciphers. This patch adds a new attribute: - HWSIM_ATTR_CIPHER_SUPPORT A u32 array/list of supported cipher types This only allows enabling/disabling cipher types listed in the (new) "hwsim_ciphers" array in mac80211_hwsim.c. Any unknown cipher type will result in -EINVAL.

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.
