Obtain the ingress device in the tuple from the route in the reply direction. Use dev_fill_forward_path() instead to get the real ingress device for this flow. Fall back to use the ingress device that the IP forwarding route provides if: - dev_fill_forward_path() finds no real ingress device. - the ingress device that is obtained is not part of the flowtable devices. - this route has a xfrm policy.

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.
