Subject: [Pana] Regarding Pana New PaC L2 Notification

If an EP uses an L2 based filtering and device IDs of PaC and EP are mac addresses then
in such a scenario, when an unathorized PaC starts sending data, EP will drop those 
packets and sends panaNewPaCL2Notification to PAA using snmp notification operation.

panaNewPaCL2Notification is defined in the draft draft-ietf-pana-snmp-05 as 

panaNewPacL2Notification NOTIFICATION-TYPE
       OBJECTS {
         spdActionExecuted,
         panaEpIfIndex,
         panaL2SourceAddress
       }
       STATUS  current
       DESCRIPTION
       "Notification that EP detected L2 traffic coming from an
       unauthorized source. "
       ::= { panaNotifications 2 }

When PAA receives NewPaCL2Notification it has to send PSR to EP.

But :
1.How can PAA send PSR to PaC when it knows only spdActionExecuted, panaEpIfIndex, panaL2SourceAddress (i.e, PAA does not know IP address of PaC yet)?
2.Why does EP need to send its PaC's L2SourceAddress to PAA?(i.e., why PAA needs to know L2 address of PaC?)
3.Does EP need to send panaNewPaCIPNotification also even when EP does L2 based filtering?(How else can PAA know PaC's IP address)

Thanks&Regards,
Nagaraju.
