David Ahern 7973d9e767 mlxsw: spectrum_router: Prevent ipv6 gateway with v4 route via replace and append
mlxsw currently does not support v6 gateways with v4 routes. Commit
19a9d136f1 ("ipv4: Flag fib_info with a fib_nh using IPv6 gateway")
prevents a route from being added, but nothing stops the replace or
append. Add a catch for them too.
    $ ip  ro add 172.16.2.0/24 via 10.99.1.2
    $ ip  ro replace 172.16.2.0/24 via inet6 fe80::202:ff:fe00:b dev swp1s0
    Error: mlxsw_spectrum: IPv6 gateway with IPv4 route is not supported.
    $ ip  ro append 172.16.2.0/24 via inet6 fe80::202:ff:fe00:b dev swp1s0
    Error: mlxsw_spectrum: IPv6 gateway with IPv4 route is not supported.

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.
