Grand Pauses in 4.3 on 750s

[lrr at princeton.UUCP]

The problem turned out to be a lack of buffers in the DEUNA.  By asserting
dedebug in the driver, we found that it was unable to put the incoming
information anywhere.  We changed the line

	#define	NRCV	7

to

	#define	NRCV	31

and all is well.  The problem did not show up on the 8600 because it
appears to be able to get the info from the DEUNA fast enough to never (?)
run out of buffer space.
