[Linuxptp-users] Unicast service recovery after link down.

[Neil M. <nm...@cc...>]

Hello,

I'm running the ptp4l unicast service on some point-multipoint radio 
devices (they don't support timestamped broadcasts). I'm finding that 
after a link-down, link-up sequence the unicast service does not 
recover. The fdtimer driving the service at the master doesn't seem to 
get rearmed. I find that the patch below seems to fix the issue for me, 
however I don't know the code well enough to be sure that its the right 
fix. I'd be grateful for any thoughts on the matter.

Best regards,

Neil Murphy.
