- cl_status is an integer. cl_lstatus is a pointer.
- Add some debugging code to dump some things the driver knows about
the adapter.
- Tell CAM that the adapter can handle more commands when a command
completes. This fixes the problem were the SIM would freeze once
the driver hit the maximum number of transactions for the device.
- Change the vendor string to COMPAQ.
- Turn of Synchronize Cache for now. It locks the controller up.

ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper

via the block interface; this merely provides a way to circumvent the
RAID functionality and access the SCSI buses directly. Note that for
somewhat obvious reasons, hard drives are not exposed to the da driver
through this interface, though you can still talk to them via the pass
driver. Be the first on your block to low-level format unsuspecting
drives that are part of an array!

Avoid some code paths in ahc_abort_scbs() if we are currently

Correctly cleanup stranded SCBs in the card's SCB array. These

Add a comment about some potential bus reset issues for target

Cleanup the hardware scb definitions a bit.
Allocate a ful 256 byte scb mapping index. This simplifies

In target mode, initialize SAVED_LUN just after we receive

Defer looking for space for a cdb packet until we are about to

rate correctly once data are availble.
aic7xxx_93cx6.c:
aic7xxx_93cx6.h:
Add the ability to write and erase the seeprom.
aic7xxx_inline.h:
Correct Big Endian handling of large cdb sizes (> 12 bytes).
Adaptec to changes in the calc_residual API.
Correct a target mode bug where we always attempted to service
the input queue even if no progress could be made due to lack
of ATIOs.
aic7xxx_osm.c:
Adaptec to new IRQ mapping API. The new API allows the core
to only enable our IRQ mapping once it is safe (sufficient
initialization) to do so.
Slap bootverbose protection around some diagnostics.
Only attempt DT phases if we are wide.
aic7xxx_osm.h:
Enable big endian support.
Adjust for IRQ API change.
aic7xxx_pci.c:
Be more careful about relying on subvendor 9005 information.
We now only trust it for HBAs. This should allow the driver
to attach to some MBs where the subvendor/device information
does not follow the Adaptec spec.
Only enable interrupts on the card once we are fully setup.
Disable external SCB ram usage on the aic7895. I have not
been able to make it 100% reliable.
Adjust to seeprom routines being properly prefixed with "ahc".
Fix a few bugs in the external SCB ram probing routine. We
need to clear any parity errors we've triggered during the
probe to avoid future, fatal, interrupts.
If we detect an invalid cable combination, pretent there are
no cable at all. This will enable all of the terminators
which is probably the safest configuration we can "guess".

-stable machine via the old-school methods):
Use __FreeBSD_version in preference to __FreeBSD__ >= N where possible.
Define a single variable mythread which is set to curproc or curthread
depending on the OS version (with a comment saying it is a white lie on
4.x since it really is a proc).
NB: __FreeBSD__ is the OS level of the host machine, not the target,
and should never be used, if possible, as __FreeBSD__ >= N.
Rev 1.56 of if_dc.c removed calls to mii_pollstat() from the dc_tick()
routine. dc_tick() is called regularly to detect link up and link down
status, especially when autonegotiating.
The expectation was that mii_tick() (which is still called from dc_tick())
would update status information automatically in all cases where it would
be sensible to do so.
Unfortunately, with authentic 21143 chips this is not the case, and
the driver never successfully autonegotiates. This is because (despite
what it says in the 21143 manual) the chip always claims that link is not
present while the autonegotiation enable bit is set. Autonegotation takes
place and succeeds, but the driver tests the link bits before it switches
off the autonegotiation enable bit, and success is not recognised.
The simplest solution is to call dcphy_status() more often for MII_TICK
calls by dropping out of the switch statement instead of exiting when
we are autonegotiating and link appears to not be present. When
autonegotiation succeeds, dcphy_status() will note the speed and fdx/hdx
state and turn off the autonegotiation enable bit. The next call to
dcphy_status() will notice that link is present, and the dc driver code
will be notified.
Macronix chips also use this code, but implement link detection as
described in the manual, and hence don't need this patch. However, tests
on a Macronix 98715AEC-C show that it does not adversely affect them.
This could be done better but is the minimal effective change, and most
closely mimics what was happening prior to rev 1.56 of if_dc.c. (Actually
I also deleted a small amount of unnecessary code while I was in the area.)

environment needed at boot time to a dynamic subsystem when VM is
up. The dynamic kernel environment is protected by an sx lock.
This adds some new functions to manipulate the kernel environment :
freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be
called after every getenv() when you have finished using the string.
testenv() only tests if an environment variable is present, and
doesn't require a freeenv() call. setenv() and unsetenv() are self
explanatory.
The kenv(2) syscall exports these new functionalities to userland,
mainly for kenv(1).

FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.
We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches. This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.
This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.
