* Some devices are particularly sensitive to interrupt
* handling latency. The DCA, for example, can lose many
* characters if its interrupt isn't handled with reasonable
* speed.
*
* To work around this problem, each device can give itself a
* "priority". An unbuffered DCA would give itself a higher
* priority than a SCSI device, for example.
*
* This is necessary because of the flat spl scheme employed by
* the hp300. Each device can be set from ipl 3 to ipl 5, which
* in turn means that splbio, splnet, and spltty must all be at
* spl5.

* Don't blame me...I just work here.
* speed. For this reason, we sort ISRs by IPL_* priority,
* inserting higher priority interrupts before lower priority
* interrupts.
