This patch-set is to support Ocelot PTP Sync one-step timestamping.
Actually before that, this patch-set cleans up and optimizes the
DSA slave tx timestamp request handling process.

Changes for v2:
	- Split tx timestamp optimization patch.
	- Updated doc patch.
	- Freed skb->cb usage in dsa core driver, and moved to device
	  drivers.
	- Other minor fixes.
Changes for v3:
	- Switched sequence of patch #3 and #4 with rebasing to fix build.
	- Replaced hard coded 48 of memset(skb->cb, 0, 48) with sizeof().

Yangbo Lu (7):
  net: dsa: check tx timestamp request in core driver
  net: dsa: no longer identify PTP packet in core driver
  net: dsa: no longer clone skb in core driver
  net: dsa: free skb->cb usage in core driver
  docs: networking: timestamping: update for DSA switches
  net: mscc: ocelot: convert to ocelot_port_txtstamp_request()
  net: mscc: ocelot: support PTP Sync one-step timestamping
