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.
