S2IO: Optimized the delay to wait for command completion
- Optimized delay to wait for command completion so as to reduce the initialization wait time. - Disable differentiated services steering. By default RMAC is configured to steer traffic with certain DS codes to other queues. Driver must initialize the DS memory to 0 to make sure that DS steering will not be used by default.
