Update of /a/cvsroot/src/sys/arch/sparc/dev
In directory pain.lcs.mit.edu:/b/tmp/cvs-serv22242

Modified Files:
	espvar.h esp.c 
Log Message:
Lots of major and minor bug fixes and changes.
- properly do MSG_IN handshaking, so we can actually receive multi-byte msgs.
- do synch negotiation (now that the above works).
- handle disconnects.
There are a few trial-and-error bits at points where the docs I have are
particularly ambiguous about the state of chip and/or SCSI bus.

Things to do:
- more cleanup
- deal with MSG_OUT phase better
- keep some "config reg 3" bits per target (ie. FASTCLK and FASTSCSI).
