freebsd-dev/sys/dev/asr/osd_unix.h
Mike Smith ef137fd32f Add the 'asr' driver, supplied by Mark Salyzyn of Adaptec (nee DPT). 
This provides support for the Adaptec SCSI RAID controller family,
as well as the DPT SmartRAID V and VI families.

The driver will be maintained by Mark and Adaptec, and any changes
should be referred to the MAINTAINER.
