While adding some PHY ID for Aquantia, I notice that there is a big problem with duplicating OPs with each PHY. The original idea to prevent this was to use mask on the PHY ID and identify PHY Family. Problem is that OEM started to use all kind of PHY ID and this is not doable, hence for PHY that have the same OPs, we have to duplicate all of them. This is present in Aquantia PHY, but is much more present in other PHY, especially in the BCM7XXX where they use a big macro for common PHYs. To reduce patch delta, I added the additional variable without adding tabs as this would have resulted in a massive patch. Also to have patch bisectable, this change has to be in one go hence I had to use this trick to reduce patch delta. Other solution to this problem were to introduce additional variables to phy_driver struct but that would have resulted in having 2 different way to do the same thing and that is not O.K. I took care to compile-test all the PHY, only exception is the unique RUST driver, where I still have to learn that funny language and I didn't had time to update it, so that is the only driver that I think require some fixup. I posted 2 example that would benefits from this change, but I can find much more in other PHY driver.
