Current igc_rar_set_index() implementation is a bit convoluted so this patch does some code refactoring to improve it. The helper igc_rar_set_index() is about writing MAC filter settings into hardware registers. Logic such as address validation belongs to functions upper in the call chain such as igc_set_mac() and igc_add_mac_filter(). So this patch moves the is_valid_ether_addr() call to igc_add_mac_filter(). No need to touch igc_set_mac() since it already checks it. The variables 'rar_low' and 'rar_high' represent the value in registers RAL and RAH so we rename them to 'ral' and 'rah', respectively, to match the registers names. To make it explicit, filter settings are passed as arguments to the function instead of reading them from adapter->mac_table "under the hood". Also, the function was renamed to igc_set_mac_filter_hw to make it more clear what it does. Finally, the patch removes some wrfl() calls and comments not needed.

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.
