Drivers that support tunnel decapsulation (IPinIP or NVE) need to configure the underlying device to conform to the behavior outlined in RFC 6040 with respect to the ECN bits. This behavior is implemented by INET_ECN_decapsulate() which requires an skb to be passed where the ECN CE bit can be potentially set. Since these drivers do not need to mark an skb, but only configure the device to do so, factor out the business logic to __INET_ECN_decapsulate() and potentially perform the marking in INET_ECN_decapsulate(). This allows drivers to invoke __INET_ECN_decapsulate() and configure the device.

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 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.
