Vladimir Oltean 8f18655c49 net: dsa: don't call ptp_classify_raw() if switch doesn't provide RX timestamping 
ptp_classify_raw() is not exactly cheap, since it invokes a BPF program
for every skb in the receive path. For switches which do not provide
ds->ops->port_rxtstamp(), running ptp_classify_raw() provides precisely
nothing, so check for the presence of the function pointer first, since
that is much cheaper.
