net: mscc: ocelot: support PTP Sync one-step timestamping
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.
