Subject: [PATCH] net: hsr: save cut-through tx timestamp of stripped skb
For a received PTP event message, there may be a cut-through tx timestamp
associated with it also. When the skb is stripped of the HSR tag and a
new skb is created, the cut-through tx timestamp is saved in the shared
redundant info area of the newly created skb.
