You can run ptp4l as a Boundary Clock on multiple interfaces at once,
and you can freely mix and match profiles on the different ports.
For example:
ptp4l -m -q -i eth0 -i eth1
or in a configuration:
[global]
# ...
[eth0]
# eth0 options...
[eth1]
# eth1 options...
The only thing I'm uncertain of is the Automotive Profile. Most of
the configuration options are per-port, but you will probably not set
the global option inhibit_delay_req.
See the man page and/or config.c to learn which options are per-port.
Thanks,
Richard
