[Linuxptp-devel] [PATCH 3/4] port: On transition to UNCALIBRATED/SLAVE only start delay request timer if delay_resp was granted

[Vincent Cheng]

From: Vincent Cheng <vsch...@gmail.com>

Sending delay requests prior to getting a delay response grant will incur 
unnecessary
delay_response_timeout errors if the remote master only responds to delay 
requests
when a delay reponse request was granted.
