Although HWTSTAMP_TX_ONESTEP_SYNC existed in ioctl for hardware timestamp configuration, the PTP Sync one-step timestamping had never been supported. This patch is to truely support it. - ocelot_port_txtstamp_request() This function handles tx timestamp request by storing ptp_cmd(tx timestamp type) in OCELOT_SKB_CB(skb)->ptp_cmd, and additionally for two-step timestamp storing ts_id in OCELOT_SKB_CB(clone)->ptp_cmd. - ocelot_ptp_rew_op() During xmit, this function is called to get rew_op (rewriter option) by checking skb->cb for tx timestamp request, and configure to transmitting. Non-onestep-Sync packet with one-step timestamp request falls back to use two-step timestamp.
