I have tested the Intel 82547L and the i210 NICs with linuxptp 1.4 and 1.5.
They work fine on our Red Hat Linux kernel make -C
/lib/modules/2.6.32-504.3.3.el6.x86_64.
But I cannot get the i350T2V2BLK to work.
It sees the correct PTP Grandmaster 0019dd.fffe.00085c, but all I get this,
even increasing tx_timestamp_timeout to 1000:
ptp4l -i eth2 -f /etc/ptp4l.conf -m -l 7
ptp4l[181.099]: eth2: SO_SELECT_ERR_QUEUE: Protocol not available
ptp4l[181.099]: port 1: UNCALIBRATED to LISTENING on FAULT_DETECTED

ptp4l[187.079]: foreign master not using PTP timescale
ptp4l[187.079]: running in a temporal vortex
ptp4l[187.079]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE
ptp4l[194.076]: port 1: delay timeout
ptp4l[194.176]: timed out while polling for tx timestamp
ptp4l[194.176]: increasing tx_timestamp_timeout may correct this issue, but
it is likely caused by a driver bug
ptp4l[194.176]: port 1: send delay request failed
...
I have installed the latest igb driver 5.1.15.
ethtool -i eth2
driver: igb
version: 5.2.15
firmware-version: 1.63, 0x80000cbb
bus-info: 0000:10:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
[root@ptp2 ~]# ethtool -T eth2
Time stamping parameters for eth2:
Capabilities:
hardware-transmit (SOF_TIMESTAMPING_TX_HARDWARE)

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)

off (HWTSTAMP_TX_OFF)
on (HWTSTAMP_TX_ON)
Hardware Receive Filter Modes:
none (HWTSTAMP_FILTER_NONE)
all (HWTSTAMP_FILTER_ALL)
I have installed an i210, which uses the same driver, and it works nicely:
ptp4l -i eth4 -f /etc/ptp4l.conf -m -l 7
