Description

For some more long-term testing or later operation, we need good statistics, such as

re-ordered or missing IP packets
Rx/Tx byte/packet count
RTT
frame underflows in IP -> E1 direction

Those stats could be interrogated via VTY, but ideally also exposed via our libosmocore statsd exporter.

Checklist

count of re-ordered or missing IP packets (rate_ctr)
overall Rx/Tx packet + byte count (rate_ctr)
RTT (stat_item)
frame underflows in IP->E1 direction
FIFO fill level both directions
time since last link recovery

Checklist item deleted (~~frame number delta of re-ordered packets~~)
Checklist item count of re-ordered or missing IP packets (rate_ctr) set to Done
Assignee deleted (~~laforge~~)

I recently introduced a larger number of rate_ctr + stat_items (fifo levels, underruns, frame substiutions, number of TS used, ...) and they are used successfully to plot performance figures.

Still, those listed in the checkbox here are not yet implemented.
