[PATCH] I2O: Adaptec specific SG_IO access, firmware access through sysfs and 2400A workaround
Changes:
- Provide SG_IO access to BLOCK and EXECUTIVE class on Adaptec
controllers
- Use PRIVATE messages in SCSI-OSM because on some controllers normal
SCSI class commands like READ or READ CAPACITY cause errors
- Use new DMA and SG list creation function
- Added workaround to limit sectors per request for Adaptec 2400A
controllers
