net: ethernet: ti: netcp_ethss: use cpts to check if packet needs timestamping
There is cpts function to check if packet can be timstamped with cpts. Seems that ptp_classify_raw cover all cases listed with "case". Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
