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 Signed-off-by: Ivan Khoronzhuk <redacted> --- drivers/net/ethernet/ti/cpsw.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
