[SCSI] 2.6 aacraid: Variable FIB size (updated patch)
New code from the Adaptec driver. Performance enhancement for newer adapters. I hope that this isn't too big for a single patch. I believe that other than the few small cleanups mentioned, that the changes are all related. - Added Variable FIB size negotiation for new adapters. - Added support to maximize scatter gather tables and thus permit requests larger than 64KB/each. - Limit Scatter Gather to 34 elements for ROMB platforms. - aac_printf is only enabled with AAC_QUIRK_34SG - Large FIB ioctl support - some minor cleanup Passes sparse check. I have tested it on x86 and ppc64 machines. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
