Therefore, -1 has to be specified to the phc_index for ethtool's get_ts_info, otherwise a wrong value will be set to the phc_index. v2: move the if (adapter->ptp_clock) section specifying phc_index to above the switch statement as suggested by Matthew Vick. adapter->ptpclock will always be NULL for 82575.
