A.4.5.7 Handling Unsupported SRB_FUNCTION_XXX

Every HwScsiStartIo routine must handle the receipt of an unsupported SRB_FUNCTION_XXX  as follows:

1. Set the input SRB’s SrbStatus to SRB_STATUS_INVALID_REQUEST.

2. Call ScsiPortNotification with the NotificationType RequestComplete and with the input SRB.

3. Call ScsiPortNotification again with the NotificationType NextRequest, or with NextLuRequest if the HBA supports tagged queueing or multiple requests per logical unit.

4. Return control.
