An SRv6 behavior instance can be set up using mandatory and/or optional attributes. In the setup phase, each supplied attribute is parsed and processed. If the parsing operation fails, the creation of the behavior instance stops and an error number/code is reported to the user. In many cases, it is challenging for the user to figure out exactly what happened by relying only on the error code. For this reason, we add the support for netlink_ext_ack in parsing SRv6 behavior attributes. In this way, when an SRv6 behavior attribute is parsed and an error occurs, the kernel can send a message to the userspace describing the error through a meaningful text message in addition to the classic error code.

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.
