We can't assert that the RX engine is idle in iscsi_done(), because it

may be called during the RX data processor, before the RX engine
transitions back to idle.  It doesn't really matter if the RX engine
isn't idle when iscsi_done() is called, because it will just pick up
where it left off on the next call.  (The same is not true for the TX
engine, so keep the TX engine assertion.)

src/net/tcp/iscsi.c

 static void iscsi_done ( struct iscsi_session *iscsi, int rc ) {
 
 	assert ( iscsi->tx_state == ISCSI_TX_IDLE );
-	assert ( iscsi->rx_state == ISCSI_RX_BHS );
-	assert ( iscsi->rx_offset == 0 );
 
 	/* Clear current SCSI command */
 	iscsi->command = NULL;
