deuna driver problems in 4.[23]

[Gail B. Hanrahan]

In re: "de0: buffer unavailable" messages --

Our poor little 730 (which runs an old 4.2 binary from mt xinu)
developed this problem late last week.  It does not seem to have
affected the running of the system (used only for driving
printers).  The DEC CE came out and swapped DEUNAs; the new
DEUNA produced the same error message, which leads me to think
that something else must be going on.

Since it is a binary-only machine (no source at all at this
site, though Calma does have a source license in Milpitas),
I can't go hacking on the DEUNA driver.  Any other suggestions
would be appreciated.
