This registers set at internal SMI address 0x1C provides extended

features like EEPROM interface, trunking, cross-chip setup, etc.

It is required on most chips. If the chip you compile the support for
|
|
doesn't have such registers set, say N here. In doubt, say Y.

Say Y to enable PTP hardware timestamping on Marvell 88E6xxx switch
|
|
chips that support it.
