It could be a driver issue. Looking on Broadcom page I see no reference to PTP or IEEE 1588. https://www.broadcom.com/products/ethernet-connectivity/network-adapters/bcm57416-1gbase-t-ic I can not tell you if the NIC supports PTP or not. Anyhow this mailing list is for linuxptp and not for Broadcom's NIC. You should try in forums for Broadcom NICs. Or Linux kernel modules forums.
