An IP packet received on a netdev with a macvlan upper whose MAC matches the packet's destination MAC will be re-injected to the Rx path as if it was received by the macvlan, and perform an L3 lookup. Reflect this functionality to the ASIC by programming FDB entries that will direct MACs of macvlan uppers to the router. In a similar fashion to router interfaces (RIFs) that are programmed upon the addition of the first IP address on an interface and destroyed upon the removal of the last IP address, the FDB entries for the macvlan are added and destroyed based on the addition of the first and removal of the last IP address on the macvlan.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
