Since the driver is for SoftIP (I mean fpga ip) default h/w configuration of this IP is frame store Configuration disabled that's in the driver making default value of this configuration as zero. If users are trying a use case where this configuration should be enabled but in the h/w it is disabled. In this case driver will warn users to enable this frame store configuration in the h/w. So that users can enable it in their h/w.
