I ran some tests with this patch. When the team interface was not
configured with the activebackup runner, ptp4l refused to start as
expected.
It started after configuring the interface to use activebackup.
When I forced it to switch to another port by setting the active link
down (I'm not sure if that is the proper way to do it), ptp4l crashes
on start.
# ptp4l -m -i nm-team
