Subject: [PATCH 2/2] net: ethernet: ti: cpsw: allow PTP 224.0.0.107 to be timestamped
Date: Fri,  6 Jul 2018 21:44:45 +0300	[thread overview]
Message-ID: <20180706184445.29111-3-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <20180706184445.29111-1-ivan.khoronzhuk@linaro.org>

Tested on AM572x with cpsw v1.15 for PTP sync and delay_req messages.
It doesn't work on cpsw v1.12, so added only for cpsw v > 1.15.

Command for testing:
ptp4l -P -4 -H -i eth0 -l 6 -m -q -p /dev/ptp0 -f ptp.cfg
where ptp.cfg:

[global]
tx_timestamp_timeout     20
