Fault in pcap_list_tstamp_types()?

[Anders Broman <anders.broman () ericsson com>]

Hi,
Playing with this function I get
pcap_list_tstamp_types, num tstamp_types 3
host
adapter_unsynced
adapter

Then trying to set pcap_set_tstamp_type(pcap_h, PCAP_TSTAMP_ADAPTER);

'eth1' (SIOCSHWTSTAMP failed: Numerical result out of range).

ethtool -T eth1
Time stamping parameters for eth1:
Capabilities:
                hardware-transmit     (SOF_TIMESTAMPING_TX_HARDWARE)
                software-transmit     (SOF_TIMESTAMPING_TX_SOFTWARE)
                hardware-receive      (SOF_TIMESTAMPING_RX_HARDWARE)
                software-receive      (SOF_TIMESTAMPING_RX_SOFTWARE)
                software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
                hardware-raw-clock    (SOF_TIMESTAMPING_RAW_HARDWARE)
PTP Hardware Clock: 1
Hardware Transmit Timestamp Modes:
                off                   (HWTSTAMP_TX_OFF)
                on                    (HWTSTAMP_TX_ON)
Hardware Receive Filter Modes:
                none                  (HWTSTAMP_FILTER_NONE)
                ptpv1-l4-event        (HWTSTAMP_FILTER_PTP_V1_L4_EVENT)
                ptpv2-l4-event        (HWTSTAMP_FILTER_PTP_V2_L4_EVENT)
                ptpv2-l2-event        (HWTSTAMP_FILTER_PTP_V2_L2_EVENT)

So it seems libpcap is reporting the availability of HW timestamp when in fact it's not available. Or am I missing 
something?
(1.6.0-PRE-GIT)
