When you use pty(N) it creates pty(N+1) ready for your use in the DEVFS,
so DEVFS is not cluttered up with hundreds of ptys you are never going to
use.
about a dev_t.
printf("%x", dev) now becomes printf("%s", devtoname(dev)) because
printing actual information about the device is much more useful then
printing a pointer to an address that would never help the developer debug.

With these knobs on, refused connection attempts are dropped
without sending a RST, or Port unreachable in the UDP case.
In the TCP case, sending of RST is inhibited iff the incoming
segment was a SYN.

didn't match the argument (p->p_pid).
While I'm at it, also fix the dupo in the format string and fix the annoying
inconsistency in all the debug-printfs wrt p_pid arguments. Change all of them
to use the %ld format specifier and cast the p_pid arguments to long.

Fix a bug in how default transfer negotiations are handled if the

Support multi-targetid on the aic7895C.
Handle errors reported through immediate notify ccbs. This includes

Properly setup CA conditions for errors such as uncorectable parity

Add a mechanism for stalling the queue of transactions to a particular

Properly bzero our softc at init time (oops).
Add more documentation on what all of the queues in our softc do.
Clear residuals for XPT_TARGET_IO/XPT_CONT_TARGET_IO calls just

Make xpt_release_devq a proper reciprocal of xpt_freeze_devq by
allowing the caller to decrement the count more than once per call.
Change the semantics of xpt_path_cmp to return 1 for a match
with a wildcard from path1 and 2 for a match with wildcards
from path2. This change doesn't affect most callers as they
only check for >=0 (exact match or one containing a wildcard).
When cleaning up a device node, ensure that there are no timeouts

mechanism should be completely revamped, but this will serve for the time

Take advantage of some new behavior in xpt_path_comp which allows the
caller to determine which path, if any, had wildcards in it that allowed
for a match to succeed. We can now use this to filter out wildcard
nodes in the EDT.
Make the amount of time we pause after writing a debug message

Change tag_id and init_id to be u_int from u_int8_t. Some topologies
