From: Vincent Cheng <vsch...@gmail.com>
In case of broken network there may be an absolute absence of delay packets.
In this scenario ptp4l log messages do not indicate anything is wrong because
the delay response timer is only activate for LOCKED servo state.
This patch expands the delay_response_timeout feature to be active in the
UNLOCKED servo state.
