[Linuxptp-users] help the newb

[David G. <dav...@po...>]

Hi,

I'm having trouble getting Linuxptp-1.3 to sync with my switch.

switch: Netgear GS716Tv2 FW=5.4.1.13 with AVB (GS716TAV-10000S) license
comp: Linux Mint 15 with Intel I210 NIC

$ lspci |grep I210
02:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network
Connection (rev 03)

$ ethtool -T eth2
Time stamping parameters for eth2:
Capabilities:
	hardware-transmit     (SOF_TIMESTAMPING_TX_HARDWARE)
	hardware-receive      (SOF_TIMESTAMPING_RX_HARDWARE)
	hardware-raw-clock    (SOF_TIMESTAMPING_RAW_HARDWARE)
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes:
	off                   (HWTSTAMP_TX_OFF)
	on                    (HWTSTAMP_TX_ON)
Hardware Receive Filter Modes:
	none                  (HWTSTAMP_FILTER_NONE)
	all                   (HWTSTAMP_FILTER_ALL)

$ lsmod |grep ptp
ptp                    18621  1 igb
pps_core               14080  1 ptp

The line 'ptp4l[162693.139]: rx_filter 1 not 12' I think means
HWTSTAMP_FILTER_PTP_V2_L2_EVENT is not a capability.

Wireshark shows the switch responding, but apparently ptp4l isn't
hearing it.

Help walk me through debugging this.  Tnks.
