[SCSI] aacraid: Series 7 Async. (performance) mode support
- Series 7 Async. (performance) mode support added
- New scatter/gather list format for Series 7
- Driver converts s/g list to a firmware suitable list for best performance on
Series 7, this can be disabled with driver parameter "aac_convert_sgl" for
testing purposes
- New container read/write command structure for Series 7
- Fast response support for the SCSI pass-through path added
- Async. status response buffer changes
