[Linuxptp-users] SOF_TIMESTAMPING_TX_SOFTWARE missing

[Sebastien <seb...@jd...>]

Hello,







I've got a new HP server, with Esxi E1000, with a NIC Broadcom NetXtreme 

BCM 57810, and VM hosting RHEL6.5







I would like it to use the Soft option to synchronize from PTP source, 

connected on Eth1.



I've installed linuxptp, and updated the NIC driver for the RHEL 6.5







Unfortunately, the software-transmit     (SOF_TIMESTAMPING_TX_SOFTWARE)



is not reported after the command ethtool -T eth1



And , using ptp4l -i eth1 -m -S shows ;







[root]# ptp4l -i eth1 -m -S



interface 'eth1' does not support requested timestamping mode.



[root]#  ethtool -T eth1



Time stamping parameters for eth1:



Capabilities:



        software-receive      (SOF_TIMESTAMPING_RX_SOFTWARE)



        software-system-clock (SOF_TIMESTAMPING_SOFTWARE)



PTP Hardware Clock: none



Hardware Transmit Timestamp Modes: none



Hardware Receive Filter Modes: none











Is it because of a NIC card compatibility or an ESXI compatibility?



Is there some description, recommendation of Linux and Hardware version to 

support linuxptp?















Thanks for your help







Regards



Sebastien
