If you're using MLS rate-limiters, I've often seen prefix
programmed in ELAM as TTL or MTU rate-limiter index,
0x0380 is MTU failure, 0x7F0A unicast ip error, 0x7FFF
ttl failure. These are typically shared with many
type of drops, so it's not 100% certain.
But unless you see real interface index or 0x7FFA
which is recirculate in my experience, it's likely wrong.

Yeah I guess most reload and thus don't see these issues.
