net: Add skb_clear_tstamp() to keep the mono delivery_time
Right now, skb->tstamp is reset to 0 whenever the skb is forwarded.
If skb->tstamp has the mono delivery_time, clearing it can hurt
the performance when it finally transmits out to fq@phy-dev.
The earlier patch added a skb->mono_delivery_time bit to
flag the skb->tstamp carrying the mono delivery_time.
This patch adds skb_clear_tstamp() helper which keeps
the mono delivery_time and clears everything else.
The delivery_time clearing will be postponed until the stack knows the
skb will be delivered locally. It will be done in a latter patch.
