Ido Schimmel 041bc0dce5 selftests: fib_nexthops: Test IPv6 route with group after replacing IPv4 nexthops
Test that an IPv6 route can not use a nexthop group with mixed IPv4 and
IPv6 nexthops, but can use it after replacing the IPv4 nexthops with
IPv6 nexthops.

Output without previous patch:

# ./fib_nexthops.sh -t ipv6_fcnal_runtime

IPv6 functional runtime

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.
