aacvar.h
Log:
Begin support for 64-bit address support and workarounds for newer cards:
- Add data structuress for doing 64-bit scatter/gather
- Move busdma tag creations around so that only the parent is
created in aac_pci.c.
- Retrieve the capabilities word from the firmware before setting
up command structures and tags. This allows the driver to decide
whether to do 64-bit commands, and if work-arounds are needed for
systems with >2GB of RAM.
- Only enable the SCSI passthrough if it's enabled in the capabilities
word in the firmware.
This should fix problems with the 2120S and 2200S cards in systems with more
than 2GB of RAM. Full 64-bit support is forthcoming.
