Error deleting PDRs when using PFCP in simulation mode (-simulate delete)

gab-arrobo commented 1 year ago

Inserting rules using the PFCP in simulation mode works as expected:

$ docker exec bess-pfcpiface pfcpiface -config conf/upf.json -simulate create

However, when deleting the rules, there is a problem deleting the PDR entries (pdrLookup method failed...)

And then, if the user wants to insert again the rules (i.e., ... -simulate create), the PDRs are not inserted
