Use automatic mode in phc2sys to automatically sync correct PHC. Another question: The sockets must be bound to the slave interface, and not to the bonding master interface, correct? If so, there is more work to do than clock_switch_phc() at fail over time. > Limits and unresolved issues: > 1. Only support bond/team active-backup > 2. Only works with phc2sys automatic mode.
