* tcp: call tcp_ack_tstamp() when not fully ackedYousuk Seung2020-06-301-2/+5
| | | | | | | | | | | | | | | When skb is coalesced tcp_ack_tstamp() still needs to be called when not fully acked in tcp_clean_rtx_queue(), otherwise SCM_TSTAMP_ACK timestamps may never be fired. Since the original patch series had dependent commits, this patch fixes the issue instead of reverting by restoring calls to tcp_ack_tstamp() when skb is not fully acked.

But people have expressed the desire to consider one of them as a backup only. Some creative solutions are currently in use: Such people are configuring multiple batman-adv mesh/soft interfaces, wire them together with some veth pairs and then tune the hop penalty to achieve an effect similar to a tunable per interface hop penalty.
