RFC 3720 says "Each Network Portal, as utilized by a given iSCSI Node,

iscsit_add_np should not check for existing matching portals, it should

return the proper error.

NACK. Your interpretation of RFC-3720 is incorrect. There is nothing
that says that a single IP address cannot be shared across multiple
TargetName+TargetPortalGroupTag endpoints.
A Network Portal is ip:port, not just IP. I'd agree two TPGs can use the
same IP as long as they listen on different ports.
But that bit I quoted seems pretty clear. How should it be alternatively
interpreted?
