FRR generated ACCEPTFILTER permit statement broken
When the ACCEPTFILTER is generated all goes well except the last line which is ip prefix-list ACCEPTFILTER seq 10 permit any.
When it starts ospf works fine and the routes are in the ospf database but zebra refuses to add them to the FIB.
After removing "seq 10" manually and restarting frr it just works as expected.
Solution proposed: Just remove "seq 10" when generating the last rule for the ACCESSFILTER from the generator code
