Brett Creeley accc1bf230 virtio_net: use control_buf for coalesce params
Commit 699b045a8e ("net: virtio_net: notifications coalescing
support") added coalescing command support for virtio_net. However,
the coalesce commands are using buffers on the stack, which is causing
the device to see DMA errors. There should also be a complaint from
check_for_stack() in debug_dma_map_xyz(). Fix this by adding and using
coalesce params from the control_buf struct, which aligns with other
commands.

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.
