Follow-up to this:
I've updated the patches on my site (ada(4) and ahci(4) do the same
thing as before but I moved the quirk printing code into a subroutine),
in addition to adding quirk printing bits for the following drivers:
* cd(4) (SCSI CD/DVD drives)
* ch(4) (SCSI tape/media changer/arms)
* da(4) (SCSI disks, also includes USB disks but quirks here are
separate from umass(4) quirks)
* sa(4) (SCSI tape drives)
da(4) was a request from another developer.
I was able to test da(4) and cd(4), but not ch(4) and sa(4) due to lack
of devices. (I do have a 2940UW SCSI controller and an AIT tape drive
laying around to test sa(4) but I can't be bothered to find the
box/unpack it and deal with all the cabling)
If anyone has ch(4) or sa(4) devices that have quirks and can test the
patches + provide feedback, I'd appreciate it. Remember: quirks are
only printed if their are defined quirks for the device.
