Send DSReq if new
PGW is selected during re-attach
The ePDG will send the delete session
request during reattach if another PGW is selected for current session. If the
same PGW is selected for current session during reattach, ePDG will not send
the delete session request to PGW and will do local purge.
In case of session creation failure during reattach, ePDG will always
trigger delete session request to PGW.
This feature can be enabled by configuring “newcall duplicate-session
notify-delete” in ePDG Configuration Mode.
