[SCSI] aacraid: Newer adapter communication iterface support
Received from Mark Salyzyn. This patch adds the 'new comm' interface, which modern AAC based adapters that are less than a year old support in the name of much improved performance. These modern adapters support both the legacy and the 'new comm' interfaces. Signed-off-by: Mark Haverkamp <markh@osdl.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
