[ Upstream commit cacfddf82b ]
In mac80211_hwsim, the probe_req frame is created and sent while
scanning. It is sent with ieee80211_tx_info which is not initialized.
Uninitialized ieee80211_tx_info can cause problems when using
mac80211_hwsim with wmediumd. wmediumd checks the tx_rates field of
ieee80211_tx_info and doesn't relay probe_req frame to other clients
even if it is a broadcasting message.
Call ieee80211_tx_prepare_skb() to initialize ieee80211_tx_info for
the probe_req that is created by hw_scan_work in mac80211_hwsim.

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.
