What ixgbe devices support HWTSTAMP_FILTER_ALL for hardware time stamping?

libpcap offers the ability to request hardware time stamping for packets and to inquire which forms of hardware time stamping, if any, are supported for an interface. The Linux implementation currently implements the inquiry by doing a ETHTOOL_GET_TS_INFO SIOETHTOOL ioctl and looking at the
