CVS commit: src/sys/dev/scsipi

["Julian Coleman" <jdc%netbsd.org@localhost>]

Module Name:    src
Committed By:   jdc
Date:           Fri Jun 19 10:30:27 UTC 2020

Modified Files:
        src/sys/dev/scsipi: if_se.c

Log Message:
First pass at making this work again.
Remove spl and add some locking around network access (needs more work).
Make sure that we consistently use the channel lock for scsipi commands.
Remove the preference for send over receive, as this can lead to deadlocks
- we only advertise 1 opening, but we can try to send before the receive is
complete in this case.
Don't use XS_CTL_ASYNC because we don't provide a buffer.
Tested on UP sparc and compile-tested on atari.
Tested with LOCKDEBUG.
Still fails with DIAGNOSTIC because we can call into the scsipi routines
from a softint.
