[ Upstream commit6f21ab3046] As it is, doing something like # iw phy phy0 interface add foobar type ibss on a firmware that doesn't have ad-hoc support just yields failures of HostCmd_CMD_SET_BSS_MODE, which happened to return a '-1' error code (-EPERM? not really right...) and sometimes may even crash the firmware along the way. Let's parse the firmware capability flag while registering the wiphy, so we don't allow attempting IBSS at all, and we get a proper -EOPNOTSUPP from nl80211 instead.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
