David Ahern says: ==================== net: Fail route add with unsupported nexthop attribute RTA_VIA was added for MPLS as a way of specifying a gateway from a different address family. IPv4 and IPv6 do not currently support RTA_VIA so using it leads to routes that are not what the user intended. Catch and fail - returning a proper error message. MPLS on the other hand does not support RTA_GATEWAY since it does not make sense to have a nexthop from the MPLS address family. Similarly, catch and fail - returning a proper error message. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
