update_plex_state:
If any subdisk in the plex is initializing, set the plex to
initializing state. This gets rid of the ugly corrupt/degraded/up
transitions which previously occurred.

logrq: save device major and minor numbers to compensate for lost
dev_t.
launch_requests: Don't issue requests which are marked
XFR_BAD_SUBDISK. This may make things easier in bre().
bre:
Rearrange.
- Change some comments
- Recognize holes in plex structure. Formerly this could lead to
incorrect write to the plex. Return REQUEST_DEGRADED on a read
request, but carry on to the bitter end on a write request, and
mark the requests for the inaccessible subdisks with
XFR_BAD_SUBDISK.
- return REQUEST_EOF if the requested transfer goes beyond the end
of the plex. This is not an error, since other plexes may go
further into the volume address space.
build_read_request:
Handle REQUEST_DEGRADED returned from bre().
sdio:
Lock buffer before issuing the requests.
will only accept partitions of type 'vinum'.
format_config: Use the new %q format option in kvprintf, thus getting
rid of some of the filthiest code I've written in a long time. Also
remove the lltoa() function.

format_config: Accept the fact that a subdisk might not be attached to
a plex, and save the config correctly.
vinum_scandisk: Scan all slices on a drive with a Microsoft partition
table. Only look at the compatibility slice if nothing was found in
the Microsoft slices.
This change removes a frequently employed method of shooting
yourself in the foot: people would decide that the Vinum drives
belonged on their own slice, and they wouldn't be able to start the
subsystem after a reboot. Documentation updates to follow.
initialize subdisks. Probably the plex-related subdisk type will die
a death.
vinumconfig.c:
Accept (and ignore) kernel state information in userland config
files. This saves a lot of error recovery and also makes it possible
to use the output of printconfig to create new configuration.
Remove checkdiskconfig(). It wasn't needed any more.
Start adding support for hot spare drives. You can't put anything on
them (yet).
Change message formats from %lld to %qd.
get_empty_sd: Initialize size to -1. Previously this was done in
config_subdisk, which is the wrong place.
start_config: set current drive, plex and volume to -1, thus stopping
update configurations from taking their defaults from old configs.
in the pathname translation procedure. This proves fatal, and can be
easily fixed. This or a similar change needs to be committed to svr4_util.h
and ibcs2_util.h. I will update ibcs2_util.h, if noone else thinks of a
better way to do this, in the same manner. I will leave svr4 to the
respective maintainer.
This closes the problem of the only crash I've been able to produce as
a user recently, except for (currently not-in-the-source tree) fd
table sharing fixes. Thanks goes to pho for his stress-testers.

It's kinda bogus that we generate a 24 (?) byte filehandle (2 x int32
fsid and 16 byte VFS fhandle) and pad it out to 64 bytes for NFSv3 with
garbage. The whole point of NFSv3's variable filehandle length was
to allow for shorter handles, both in memory and over the wire. I plan
on taking a shot at fixing this shortly.

o use vp->type rather than vaddr.type and eliminate call to

point.

I observed some anomalous behavior while testing a 3c905C with a
Dell PowerEdge 4300/500 dual PIII 500Mhz system. The NIC would seem
to work correctly most of the time but would sometimes fail to receive
certain packets, in particular NFS create requests. I could mount
an NFS filesystem from the PowerEdge and do an ls on it, but trying
to do a "touch foo" would hang. Monitoring traffic from another host
revealed that the client was properly sending an NFS create request
but the server was not receiving it. It *did* receive it when I
ran the same test with an Intel fxp card.
I don't understand the exact mechanics of this strange behavior, but
resetting the receiver and transmitter seems to get rid of it. I used
to perform an RX and TX reset in xl_init(), but stopped doing it there
because on 3c905B and later cards this causes the autoneg session to
restart, which would lead to the NIC waiting a long time before exchanging
traffic after being brought up the first time. Apparently the receiver
and transmitter resets should be performed at least once when initializing
the card.
Hopefully this will cure problems that people have been having with the
3c905C -- this was the only strange behavior that I have observed with
the 3c905C so far which does not appear with the 3c905B or 3c905.
