[PATCH net-next 02/10] net: dsa: microchip: add the number of periodic signals to chip infos

microchip ksz series ethernet switch driver, networking drivers, networking [dsa], the rest · Maintainers:

The number of periodic signals available is hardcoded to 3 while KSZ8463 can produce 12 different periodic signals. Add an n_per_out attribute to the struct ksz_chip_data to make this setting configurable.
