Uses the Linux Netlink interface to improve robustness and availability of
sfptpd when used over Linux bonded interfaces.
- As long as there is a link available,
sfptpdwill remain active in the PTP_SLAVE state.
- If all bonded links are down
sfptpdwill remain active in the PTP_LISTENING state and will activate the no-interface alarm.
- When a failed bond link is restored,
sfptpdwill resume, changing to a PTP_SLAVE state if the previous state was PTP_LISTENING.
- If an adapter/interface is swapped out/in,
sfptpdwill identify the new interface(s) and continue.
