SERDES_MAX is a valid value to index ctrl->phys in drivers/phy/mscc/phy-ocelot-serdes.c. But, currently, there is an out-of-bounds bug in the mentioned driver when reading from ctrl->phys, because the size of array ctrl->phys is SERDES_MAX. Partially fix this by updating SERDES_MAX to be SERDES6G_MAX + 1. Notice that this is the first part of the solution to the out-of-bounds bug mentioned above. Although this change is not dependent on any other one.
