Currently, userland has no methods to query which timestamping features are supported by the mcp251xfd driver (aside maybe of getting RX messages and observe whether or not hardware timestamps stay at zero). The canonical way for a network driver to advertise what kind of timestamping it supports is to implement ethtool_ops::get_ts_info(). Here, we use the CAN specific can_ethtool_op_get_ts_info_hwts() function to achieve this. In addition, the driver currently does not support the hardware timestamps ioctls. According to [1], SIOCSHWTSTAMP is "must" and SIOCGHWTSTAMP is "should". This patch fills up that gap by implementing net_device_ops::ndo_eth_ioctl() using the CAN specific function can_eth_ioctl_hwts().

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.
