[Linuxptp-devel] [PATCH] Reset delay timer when switching to P2P delay mechanism.

[Miroslav Lichvar]

When ptp4l was configured to use the auto delay mechanism and the first
pdelay request was not received in the slave or uncalibrated state, it
would not make any pdelay requests itself, because there was no delay
timer running.

Applied.
