This device does not remember its MAC address, so add a possibility to get it from the platform. If it fails, generate a random address. This will provide a MAC address early during boot without user space being involved. Also remove extra calls to is_valid_ether_addr(). Made after suggestions by Andrew Lunn: 1) Use eth_hw_addr_random() to assign a random MAC address during probe. 2) Remove is_valid_ether_addr() from moxart_mac_open() 3) Add a call to platform_get_ethdev_address() during probe 4) Remove is_valid_ether_addr() from moxart_set_mac_address(). The core does this v1 -> v2: Handle EPROBE_DEFER returned from platform_get_ethdev_address(). Move MAC reading code to the beginning of the probe function.

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.
