Version 6.1.6 of the aic7xxx driver availalbe

As always, the latest version of this driver is availalbe here:

http://people.FreeBSD.org/~gibbs/linux/

Complete CHANGELOG is now available at the above URL.

I try to filter though LK as often as I can, but for
best response, please email issues regarding this driver to
me directly.

Changes since 6.1.5 include:

        o Firmware generation is now a tunable option
          defaulting to OFF. Don't turn this on unless
          you really have a reason to re-agenerate the
          firmware (e.g. you are actively developing it).

        o aicasm Makefile changes from Alan Cox that
          attempt to make aicasm compilable on more
          distributions.

        o On some chips, at least the aic7856, the transition from
          MREQPEND to HDONE can take a full 4 clock cycles. Test
          HDONE one more time to avoid this race. We only want our
          FIFO hung recovery code to execute when the engine is
          really hung. This makes the aic7856 work again on systems
          affected by the PCI 2.1 retry bug.

        o Modify our interrupt handler so that optimizations
          that rely on level sensitive interrupts are disabled
          when edge triggered interrupts are in use. This
          affected the 284X and some EISA installations where
          level sensitive interrupts are disabled.

        o Staticize some rogue symbols. All exported symbols
          have either an "ahc" or "aic7xxx" prefix to avoid
          potential conflicts with other modules.

        o Fix the sorting of driver instances so that even
          if PCI devices are presented to the driver in a
          very strange order, it still works. In the past,
          we relied on function 0 of a device being seen prior
          to function 1. This should make the channel b primary
          BIOS option functional again.

        o Add a crude hack to make modunload/modload cycles work
          now that we are using the new PCI methods. We must
          detach our driver from each PCI device referenced by
          a call to our release method. The PCI code doesn't have
          a method to do this, so we muck with the pci_dev ourselves.

        o Deregister our PCI driver when aic7xxx_release releases
          the last host instance.

        o Only adjust our goal negotiation settings if the device
          is actually present. This prevents a disconnected lun
          that does not claim to support negotiations from messing
          up the settings for a successfully probed lun whose inquiry
          data properly reflects the abilities of the device.

        o Set the device structure as releasable should the inquiry
          come back with anything other than lun connected. We
          should also do this if the device goes away as evidenced
          by a selection timeout, but as we can't know if this
          condition is persistant and there is no guarantee that
          the mid-layer will reissue the inquiry command we use
          to validate the device, I've simply added a comment
          this effect.
