l2tp_xmit_skb has a number of failure paths which are not reflected in the tunnel and session statistics because the stats are updated by l2tp_xmit_core. Hence any errors occurring before l2tp_xmit_core is called are missed from the statistics. Refactor the transmit path slightly to capture all error paths. l2tp_xmit_skb now leaves all the actual work of transmission to l2tp_xmit_core, and updates the statistics based on l2tp_xmit_core's return 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.
