997f6ab3d7 There seems to be some problems, particularly on alpha, with 
FAST POSTING enabled for parallel SCSI. Be sure about things
and disable it for now.

65b024e1bf Redo FC target mode dma routine to try and generate an extra CTIO 
in the not so odd case of Moving Data *AND* Sending Status in last CTIO *AND*
status is a CHECK CONDITION *AND* we have Sense Data to send.

92a1e54959 Clean up some debug printing. Find the correct lun when SCCLUN is 
defined. If we complete with a check condition but no sense data,
say we had an AUTOSENSE failure.

ea49c6e4fe These are platform independent functions for target mode support. 
This is just a first pass at this and is likely to change a bit
over the next month.

0615a54798 These are platform independent definitions for target mode support- 
code gratefully borrowed from Patrick Stirling who did a lot of the
grunt work on this years ago. There are also some beginnings of
swizzle macros in case we go to a big endian machine. This is just
a first pass at this and is likely to change a bit over the next

d81ba9d532 Make a static chain of isp softcs- gdb usage becomes a lot easier. 
Add in a very large amount of target mode support code- this is just
a first pass at this. It's a difficult thing because some of the code
can be in platform independent areas (see isp_target.?) but a lot has
to be in platform dependent areas because of not only the tight coupling
of received commands/events and the specific OS subsystem but because
the platform independent code has (deliberately) no event/wait mechanisms.

ac1fd1487e Raise default FCP logintime to 60 seconds. Move the position 
of where we could have seen the loop up at least once so it
makes sense. Change some stuff in ispscsicmd so we don't get
stuck there if the loop has never come up yet. Add in some
target mode support code.

9e11e5bea2 Support target mode operations. This involves having some variant 
dma mapping callback routines to select from as target mode
entries are handled a fair bit differently from normal initiator
mode entries.

38dace9790 Clean up stupidity in the isp_handle_other_response function- indexes 
of queue entries have to be at least 16 bits now! If we're running
a 2100 less than rev 5, turn off loop fairness (per Qlogic errata). Fix
typo in checking against 2200 F/W revision. Slightly fix/reorder fabric
login stuff. Change to usage of isp_getrqentry for code clarity. Add some
defensive dual bus assumptions. Various cleanups, etc...

840e8002a0 Add a isp_getrqentry inline function (that is, find the next available 
request queue entry if any are left).

80ae565585 Fix some includes for when we (eventually) get target mode working again. 
Role the core version minor number. Change the arguments to the dma
setup function to use a u_int16_t for the output request loop pointer
(truly amazing that this hasn't blown up in anyones face so far). Do
some shuffling around of some items.

28e9826fd4 Put *back* the f/w, this time with a BSD style licence as approved 
by Qlogic. The firmware is now also kept from compiling by default
unless some config options are set.

While we're at it, roll the 2200 f/w to 2.01.0. Still need to get the
1.17.26 2100 f/w working as it solves a lot of problems but it doesn't
want to work yet with this driver (:-)).

9637d68c97 Fix dmasetup functions to have 16 bit queue indices. Get the chip revision 
out of the PCI CLASS reg and store it in the softc. Use the getenv_quad
function to get a WWN override from the environment. Look for a config
value for same. Make slightly less lame the wwn seed construction.

a3f09ae6e1 Remove calls to alpha_register_pci_scsi(). After Mike's recent boot 
changes, it no longer exists and is preventing alpha kernels from building.

2668d67e9c I was misinformed. I cannot get away from specifying tags for FC. Some devices 
are happy w/o them- some are unhappy (IBM drives).
