Multicast routing is today handled in the input path. Locally generated MC packets don't hit the IPMR code today. Thus if a VXLAN remote address is multicast, the driver needs to set an OIF during route lookup. Thus MC routing configuration needs to be kept in sync with the VXLAN FDB and MDB. Ideally, the VXLAN packets would be routed by the MC routing code instead. To that end, this patch adds support to route locally generated multicast packets. The newly-added routines do largely what ip6_mr_input() and ip6_mr_forward() do: make an MR cache lookup to find where to send the packets, and use ip6_output() to send each of them. When no cache entry is found, the packet is punted to the daemon for resolution. Similarly to the IPv4 case in a previous patch, the new logic is contingent on a newly-added IP6CB flag being set.

README
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 reStructuredText 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.
