This patch fixes some register overwriting when dumping registers via ethtool. We have a total of 16 RAL registers, starting at offset 139. So RAH offset should be 139 + 16 = 155, not 145. As result some RAL registers are overwritten. Likewise, RAH registers are also overwritten by TDBAL, TDBAH, TDLEN, and TDH registers. To fix this bug while preserving the ABI, this patch re-writes RAL and RAH registers at the end of 'regs_buff' and bumps regs->version. It also removes some pointless comments in the middle of igc_set_regs().

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.
