Add support for RTA_VIA and allow an IPv6 nexthop for v4 routes: $ ip ro add 172.16.1.0/24 via inet6 2001:db8::1 dev eth0 $ ip ro ls ... 172.16.1.0/24 via inet6 2001:db8::1 dev eth0 For convenience and simplicity, userspace can use RTA_VIA to specify AF_INET or AF_INET6 gateway. The common fib_nexthop_info dump function compares the gateway address family to the nh_common family to know if the gateway should be encoded as RTA_VIA or RTA_GATEWAY.

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.
