TX timestamps were added to the can_put_echo_skb() function of can_dev
modules in [1]. However, vcan and vxcan do not rely on that function
and as such do not offer TX timestamping.
While it could be arguable whether TX timestamps are really needed for
virtual interfaces, we prefer to still add it so that all CAN drivers,
without exception, support the software TX timestamps.
Add a call to skb_tx_timestamp() in the vcan_tx() and vxcan_xmit()
functions so that the modules now support TX software timestamps.

tx timestamps")

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.
