Ido Schimmel 8bcfb4ae4d selftests: forwarding: Fix failing tests with old libnet
The custom multipath hash tests use mausezahn in order to test how
changes in various packet fields affect the packet distribution across
the available nexthops.

The tool uses the libnet library for various low-level packet
construction and injection. The library started using the
"SO_BINDTODEVICE" socket option for IPv6 sockets in version 1.1.6 and
for IPv4 sockets in version 1.2.

When the option is not set, packets are not routed according to the
table associated with the VRF master device and tests fail.

Fix this by prefixing the command with "ip vrf exec", which will cause
the route lookup to occur in the VRF routing table. This makes the tests
pass regardless of the libnet library version.

Fixes: 185b0c190b ("selftests: forwarding: Add test for custom multipath hash with IPv4 GRE")

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.
