Update to qlogicisp driver [PATCH]
daemon@ATHENA.MIT.EDU (Michael Griffith)

From: Michael Griffith <grif@cs.ucr.edu>

Date: Thu, 29 May 1997 06:48:29 -0700 (PDT)
Here is a minor update to the qlogicisp driver. Some of the error
handling is slightly different and 4k is saved via the __initfunc and
__initdata mechanism.

configuration. As shipped, it provides a balance between speed and
function. If there are any problems, try setting SLOW_CABLE to 1, and
then try changing USE_IRQ and TURBO_PDMA to zero. If you are familiar
