- Move the command timeout check from a separate repeating timeout to the
kthread since the kthread is already running periodically.
- Move printing the hardware print buffer to the kthread.
- Properly shut down the kernel thread on detach.
- Detach the child array devices on detach.
- Don't issue a controller halt command on detach. Doing so requires a PCI
reset to wake the controller back up. The driver can now be unloaded as
long as CAM support is not enabled.
similar patch has been in 4.x for a while, but is more hacky there.)
For this to work, vinum has to be loaded early (e. g. from
boot/loader), for obvious reasons. If the kernel env variable
(aka. loader variable) "vinum.autostart" is set, vinum then asks the
sysctl kern.disks for all available disks in the system, and scans
them for possible vinum headers.
For statically compiled kernels, this behaviour can be obtained even
without boot/loader by using "options VINUM_AUTOSTART" (though this is
not the recommended way).
Alternatively, the 4.x way to specify "vinum.drives" is also supported.
No further hacks (like the 4.x "vinum.root" variable) are needed,
since in 5.x, mountroot() asks back at the drivers to have them
resolve the name of the root FS into a dev_t (using the dev_clone
eventhandler).
(The MFC reminder below is for a partial MFC for vinum.autostart, the
rest is already there in 4.x.)

of knowing data size transformations of feeder chain and in some cases
this means too much data is pulled through chain, eg converting input
stream from 16bits to 8bits on 16bit only h/w.

using the Rhine's internal shift registers which are designed
for the job. This reduces the amount of time we wait around shifting
bits, and seems to work better with some chips.
Also, provide a workaround for some newer cards which report fake PHYs
at multiple addresses. (As more cards are ID'd, I'm sure this part
of the code will have to be expanded to cover more cases.)

This patch has been tested by Thomas and other for more than a month now,
and all (known) hangs seem to be solved.
Thomas's explanation of the patch:
* Fix the problem with the printing of the RX-error.
* Code from if_fet do better deal with the RX-recovery including a
timeout of the RX-turnoff.
* The call to vr_rxeof before vr_rxeoc have been moved to a point
where the RX-part of the chip is turned off. Otherwise there is a
window where new data could have been written to the buffer chain
before the RX-part is turned off. If this happens the chip will see
a busy rx-buffer. I have no evidence that this have occured but
god knows what the chip will do in this case!
* I have added a timeout of the TX-turnoff. I have checked and in
my 900 MHz system the flags for turnoff (both RX & TX) is seen at
the first check in the loop.
* I could see that I got the VR_ISR_DROPPED interrupt sometimes and
started to thinking about this. I then realized that no recovery is
needed for this case and therefore I only count it as an rxerror
(which was not done before).
* Finally I have changed the FIFO RX threshhold to 128 bytes. When I
did this the VR_ISR_DROPPED interrupt went away. Theory: The chip
will receive a complete frame before it tries to write it out to
memory then the RX threshold is set to store'n'forward. IF the frame
is large AND the next rx frame also is large AND the bus is busy
transfering a TX frame to the TX fifo THEN the second received
frame wont fit in the FIFO and is then dropped. By having the RX
threshold set to 128 the RX fifo is emptied faster.
