[j-nsp] L3 incompletes

[Bit Gossip]

experts,
we are experiencing a constant presence of "L3 incomplete" on a 1 Gige
PIC. This is ~1 every 5 mins. Any idea what can be the reason?

The Junos doc says "This counter increments when the incoming packet
fails Layer 3 (usually IPv4) checks of the header. For example, a frame
with less than 20 bytes of available IP header would be discarded and
this counter would increment."
This means that L2 is ok so also physical layer is ok?

Thanks!
