Subject: [PATCH net-next v4 01/10] net: pcs: xpcs: Move native device ID macro to linux/pcs/pcs-xpcs.h

From: Serge Semin <[email-masked]>
Date: Mon, 1 Jul 2024 21:28:32 +0300

One of the next commits will alter the DW XPCS driver to support setting a
custom device ID for the particular MDIO-device detected on the platform.
The generic DW XPCS ID can be used as a custom ID as well in case if the
DW XPCS-device was erroneously synthesized with no or some undefined ID.
In addition to that having all supported DW XPCS device IDs defined in a
single place will improve the code maintainability and readability.

Note while at it rename the macros to being shorter and looking alike to
the already defined NXP XPCS ID macro.
