Jesper Dangaard Brouer d1a00c9bb1 dpaa2-eth: fix return codes used in ndo_setup_tc
[ Upstream commit b89c1e6bdc73f5775e118eb2ab778e75b262b30c ]

Drivers ndo_setup_tc call should return -EOPNOTSUPP, when it cannot
support the qdisc type. Other return values will result in failing the
qdisc setup.  This lead to qdisc noop getting assigned, which will
drop all TX packets on the interface.

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.
