The fp_ops_reset was targeting who violate invocation, so it contain an error log and stack-dump.
It's not suitable for this error recovering scenario.
I've also considered expansion (e.g. add extra parameter for fp_ops_reset), but there are also
other callbacks (e.g. rx_queue_count) should adjust, and make all not simple but complicated.
