sfptpddaemon must be terminated before upgrading the adapter firmware. Following firmware upgrade the adapter driver should be reloaded.
- If onload is installed:
# onload_tool reload
- If onload is not installed:
# modprobe -r sfc # modprobe sfc
ethtool -tcommand is disruptive, and should not be used while
sfptpdis running. It takes the interface offline, and so interrupts service to it. It also resets the adapter clock back to the UTC epoch.
