According to the E825C specification, SBQ address for ports on a single complex is device 2 for PHY 0 and device 13 for PHY1. For accessing ports on a dual complex E825C (so called 2xNAC mode), the driver should use destination device 2 (referred as phy_0) for the current complex PHY and device 13 (referred as phy_0_peer) for peer complex PHY. Differentiate SBQ destination device by checking if current PF port number is on the same PHY as target port number. Adjust 'ice_get_lane_number' function to provide unique port number for ports from PHY1 in 'dual' mode config (by adding fixed offset for PHY1 ports). Cache this value in ice_hw struct. Introduce ice_get_primary_hw wrapper to get access to timesync register not available from second NAC.

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 reStructuredText 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.
