Arguments in favour:
- Dave likes it;
- it wouldn't harm to add it to the default metric.
Arguments against:
- it requires two extra calls to clock_gettime for each packet sent,
which is expensive on MIPS before kernel 4.5 and musl 1.1.13;
- it adds 8 octets to each HELLO and IHU TLV;
- it might cause oscillations in topologies we didn't envision;
- it adds another moving piece;
- it's not an RFC.
So I'm hesitating. I'll probably wait until 4.5 and 1.1.13 are in OpenWRT
and have been deployed.
