I wonder if putting it under TX errors would make sense.
This is where Juniper classifies the error, and it would also
fit on same line, avoiding adding more clutter.
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 etc.
link/ether ............ brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
134705 758 0 0 0 0
RX errors: length crc frame fifo missed
0 0 0 0 0
TX: bytes packets errors dropped carrier collsns
77374 731 0 0 0 0
TX errors: aborted fifo window heartbeat transition
0 0 0 0 4
The risk is break some screen scraping script, but that doesn't
seem to be that big an issue for adding one column.
The columns also need some re-aligning here but that is different
correctness issue.
