I should have been more clear as I was wondering about different types of PCS IPs (i.e. different vendors and such). We are in the same case as the Marvell mv88e6390 family, it seems, and we treat this directly in the Lynx PCS module by a 'switch case' statement by the interface type. The MAC driver just calls the functions, no choosing necessary on its part, all of that is done by the PCS module. Ioana
