SCSI_NCR_DFLT_TAGS can be specified in the kernel config file
and sets the default number of tags per disk drive.
A value of 0 means "no tags".
Minor correction in debug messages: Values from the msg_in
buffer were being printed in the msg_out trace message ...
The code outputs the dc then calls the device specific externalize
routines to fill in the dc_data area. The old code assumed that dc_data
started one byte from the end of the dc, but with the compiler optimizing
alignment and padding, this isn't always the case. Do an explicit
&(dc.dc_data) - &dc. This fixes lsdev -c which must have been broken
for some time.
- Call eisa_registerdev as soon as we have a device match. This allows the
"eisa_add_*" routines to tweak kdc_datalen as the kdc grows and shrinks.

when a connection enters the ESTBLS state using T/TCP, then window
scaling wasn't properly handled. The fix is twofold.
1) When the 3WHS completes, make sure that we update our window
scaling state variables.
2) When setting the `virtual advertized window', then make sure
that we do not try to offer a window that is larger than the maximum
window without scaling (TCP_MAXWIN).

(1) The reads are always done from the first n/2 disks.
(2) Each write is done twice, to the "data" disk (in the first half) and
the "mirror" disk (in the second half).
ccdbuffer() now takes an extra argument (struct ccdbuf **) and stores
the pointer to ccdbuf in there. In case of a mirrored write, it
allocates and stores two pointers. The "residual" is also doubled
for mirrored writes so that ccdiodone() can correctly tell when all
the writes are done.

Keep a 1-in-16 smoothed average of the length of each tick. If the
CPU speed is correctly diagnosed, this should give experienced users
enough information to figure out a more suitable value for `tick'.

This should correctly probe both functions of the Intel 82371FB chip,

1) The calculation didn't account for NMBCLUSTERS, so if a large number of
clusters was specified, it would leave little or no space for kernel
malloc.
2) It was bogusly restricted to v_page_count. This doesn't take into
account the sparseness of the malloc area and would have caused
problems on machines with small amounts of memory. It should probably
instead be changed to set the malloc limit to be constrained by
the amount of memory, but I didn't do this.
since setting up the DMA is too costly. Restructure for efficiency.
Pause the sequencer when a parity error occurs so that the kernel driver
knows during which phase the error was encountered.
