Subject: [PATCH net-next v2 03/12] net-timestamp: reorganize in skb_tstamp_tx_output()
From: Jason Xing <kernelxing@...cent.com>
It's a prep for bpf print function later. This patch only put the
original generating logic into one function. No functional changes.
Signed-off-by: Jason Xing <kernelxing@...cent.com>

My thought is keeping each patch small helps people to review.
