[ Upstream commita6a0974aae] The PF controls the set of queues that the RDMA auxiliary_driver requests resources from. The set_channel command will alter that pool and trigger a reconfiguration of the VSI, which breaks RDMA functionality. Prevent set_channel from executing when RDMA driver bound to auxiliary device. Adding a locked variable to pass down the call chain to avoid double locking the device_lock.

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.
