ROA tables have now an auxiliary table

Browse Source 
There is an IP table for every ROA table, holding special records
combining all known ROAs for every top-prefix.

The ROA digestor is now an IP digestor, running over the auxiliary
table.

This settle time applies to ROA table changes where a trie is generated

<ref id="bgp-export-table" name="export table"> (for respective

<tag><label id="rtable-min-settle-time">roa settle time <m/time/ <m/time/</tag>
Minimum and maximum settle times, respectively, for ROA table changes.
The automatic reload is triggered after the minimum time after the last
ROA table change has been received but not later than the maximum time after
first unprocessed ROA table change. Therefore with default values, the
automatic reload happens 1 second after the ROA table stops updating, yet if it
were to be later than 20 seconds after the ROA table starts updating,
the automatic reload is triggered anyway. Default values: <cf/1 s 20 s/.
You have to always provide both values.
