  10 Since this function is a simple helper, we do not need to pass a full
  11 dsa_switch structure, we can directly pass the mv88e6xxx_chip structure.
  12 Doing so will allow to share this function with any other function
  13 not manipulating dsa_switch structure but needing info about number of
  14 internal phys
