Subject: [PATCH] Enable 16-bit CDBs for aic7xxx/aic79xxx
Date: Mon, 23 Jul 2007 10:47:23 +0200	[thread overview]
Message-ID: <46A46B1B.4010306@suse.de> (raw)

[-- Attachment #1: Type: text/plain, Size: 438 bytes --]

Hi James,

this patch enables 16-bit CDBs for aic7xxx and aic79xx. aic7xxx actuallys
supports up to 32-bit CDBs, so it might be that aic79xx does that, too.
But this would include some more hacking, so this is way easier.

Please apply.

Cheers,

Hannes

Enable 16-bit CDBs for aic7xxx/aix79xx

The patch enables support for 16-bit CDBs in aic7xxx and aic79xx.
aic7xxx can actually support up to 32-bit CDBs, should they ever see
the light of day.
