tape driver. Basically, we'll report what we can for resid, dsreg will
reflect RDONLY and MOUNTED, and erreg will retain the last seen Sense Key.
An MTIOCGET will clear these.
takes to do IELEM can be proportional to the number of elements, but is
also affected by wierd things like how readable the barcodes on the
media are. There are worst case scenarios I've seen where there are
white labels on the back of tapes with pencilled in labels which is
*just* close enough to being a bar code that an Exabyte 120 would
peer at them myopically and long enough for a *really* long time to
pass in inventorying the jukebox.
I've upped the limit to be proportional to 5 minutes per element. That
is long enough that someone I'm sure will complain about "you wait
to long and should time out" for broken h/w.
As is also noted in the PR, there are a lot of other issues here. It's
really also a question as to whether to update this driver or go
with CAM's driver. This one doesn't have switching between block
descriptors and not, doesn't support volume tag setting, and so on.
Time is limited. This PR should have been closed and fixed right away,
tho.
(1.44) missed a test for the right interface, making some machines answer
to some bogus arp requests (like for WHO-HAS 127.0.0.1).
The quick patch in 1.46-1.47 does not work for so-called "unnumbered"
interfaces, that is, (point-to-point) interfaces that share their local
address with another (e.g., the Ethernet) interface.
We add a macro to in_var.h, to step (in the current implementation) through
the hash chain and fine more entries with the same address, and use that
in if_arp.c to find one which belongs to our interface.
reading the DIO device ID at select code 7, but rather hard-wire the ID
to the IHPIB ID. This prevents us reading what might look like a valid
ID to another device when IHPIB is present. (IHPIB doesn't always return
a correct device ID, grumble.)

Remove support (ran out of space) for: ahc and bha. SCSI must be ncr or isp.
This will be fixed soon by defining an optional, two-floppy install
alternative.
