The purpose of the netif_is_down() helper was to ensure that the network
interface used was still up when performing the transmission. What it
actually did was to check if _all_ interfaces were up. This was not
noticed at that time because I did not use interfaces at all before
discussing with Alexander Aring about how to handle coordinators
properly.
Drop the helper and call netif_running() on the right sub interface
object directly.

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.
