Bug Description
The currently deployed implementation of PTP (Precision Time Protocol) does not support link aggregation.
Severity: Major - PTP does not work and will show alarm on hosts with lag
Steps to Reproduce: Configure PTP on a system with lagged management or oam interfaces.
Expected Behavior: No alarms and PTP works
Actual Behavior: PTP alarm is raised and PTP timestamping is not working for that host. If on a controller(s) then there is no accurate master and there may also be PTP Out-Of-Tolerance alarms raised on some/all subordinate hosts.
Reproducibility: Intermittent
System Configuration: Any system type with PTP configured
Branch/Pull Time/Commit: Current stream 19.01
Last Pass: Never
Timestamp/Logs: PTP logs are in user.log and daemon.log
Test Activity: collectd PTP monitor plugin development testing

Marking as release gating given LAG deployments are fairly common for hardware redundancy reasons
