validate_add_rxsa() did not originally contain that requirement. It does exist in validate_add_txsa(), which means that providing a PN is necessary only when creating TXSA. When creating an RXSA without providing a PN it will be set to 1 (init_rx_sa+15). This is the original behavior which of course can be changed. - Era.
