CVS commit: syssrc/sys/dev

[Manuel BOUYER <bouyer%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   bouyer
Date:           Sat Apr 27 17:39:52 UTC 2002

        syssrc/sys/dev/ic: esiop.c esiopvar.h
        syssrc/sys/dev/microcode/siop: esiop.ss

Log Message:
Implement a ring for the completed commands. This avoid a (problematic only
if error occurs after status is collected) race condition
when using the status byte to detect completed commands (a command descriptor
could be recycled before the device disconnected), and make the
interrupt routine handling completed commands more efficient (no need to
scan target * lun * tag array any more).
