Commit4dfb998264("tsn: Fix build.") fixed compilation with const dev_addr. In tsnep_netdev_set_mac_address() the call of ether_addr_copy() was replaced with dev_set_mac_address(), which calls ndo_set_mac_address(). This results in an endless recursive loop because ndo_set_mac_address is set to tsnep_netdev_set_mac_address. Call eth_hw_addr_set() instead of dev_set_mac_address() in ndo_set_mac_address()/tsnep_netdev_set_mac_address() to copy the address as intended.

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.
