This driver was mostly written by Doug Ambrisko and Julian Elischer and
I would like to thank Whistle for yet another contribution. And my
aplogies to them for me sitting on the driver for so long (2 months).
Also, many thanks to Reid Augustin from NetChip for providing me with a
prototype of their 1080 chip.
Be aware of the fact that this driver is very immature and has only been
tested very lightly. If someone feels like learning about Netgraph however
this is an excellent driver to start playing with.

The problem seems to be that the HP burners sometimes return
ready when they actually are not, the solution is to not use
immediate mode on the closing commands. This is suboptimal
for real burners, in that they now hog the ATA bus for possibly
minutes, where its really not nessesary, *sigh*.
not u_long. On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().
Note that if_aue doesn't strictly depend on usb because it uses the
method interface for calls rather than using internal symbols, and
because it's a child driver of usb and therefore will not try and do
anything unless the parent usb code is loaded at some point. if_aue does
strictly depend on miibus as it will fail to link if it is missing.
53C810 non 'A', 53C815 and 53C825 non 'A' are now
attached by the driver (by default).
The driver uses a different SCRIPTS set based on
MEMORY MOVE instructions for these chips.
2 SCRIPTS sets (firmwares) numbered #1 and #2 are
used for the whole support of the 53C8XX family
to get possible:
- FW #1 : Only based on MEMORY MOVE instructions.
Selected for 810, 815, 825.
- FW #2 : LOAD/STORE based. This is the firmware
also used by previous driver versions.
Selected for other chips.
When both `ncr' and `sym' are configured, `sym'
will now attach all the 53C8XX devices by default.
Previous balancing between `ncr' and `sym' can be
preserved by:
- Either editing sym_conf.h and commenting the
following compile option:
#define SYM_CONF_GENERIC_SUPPORT
(This also saves about 3.5Kb of kernel memory).
- Or setting kernel config option
SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)
first. This will fix a few cards that hang on the WD probe. He tells
me that PAO went one step farther and removed the WD proble completely
and none of the cards in the 2.x database broke in PAO3. Since I'm
more conservative in this code, I'm just swapping the order, which he
said also fixed his problem.

report_params and update params move to repparams/upparams
Tidied up old #define's
Got rid of old DPRINTF, made printf's RAY_PRINTF and panic's RAY_PANIC
All code KNF
Removed checking the ECF_TO_HOST area in ray_init - this gets hosed
when someone updates/read a parameter from the card so causes
unneeded grief. This required moving the tib check into ray_attach.
Changed handling of interface flags in ioctl so that promiscous mode
changes are only done as needed.
Sequences of comq entries can be added to an array and automatically
dealt with - used in ray_init_user and others.
Moved IFF_RUNNING checks from the comq commands to com_runq - still
not sure what to do so we PANIC - will be fixed.
ray_sj now checks to see if any of the parameters it can update can be
updated.
ray_sj_done now updates parameters to the current n/w set if we changed
them earlier. I was being a bit thick in earlier comments as to why this
check was done - the ECF never changes the parameters.
Assocication with APs is handled outside of ray_sj - need to add
WEP stuff if I ever get my hands on an AP.
ray_stop, ray_unload and ray_reset are currently broken - reset isn't used anyway.
ray_tx_XXX and ray_rx only have cosmetic changes.
Interrupt handler now gets command out of ccs. This is so ray_intr_ccs and
ray_intr_rcs don't need to remap CM (I'm trying to roll things up a bit as
it must be slowing us down).
ray_intr_ccs just vectors commands to functions or error checks - a
jump table could replace it in ray_intr.
Ditto for ray_intr_rcs.
mcast is currently broken - I need to do more work for ALLMULTI etc. This is reasonably easy to fix becuase of the comq array stuff.
Added a few more checks into repparams so that it is firmware version aware. It also uses the new comq framework.
Parameter updating is also much better with the update parameter return routine re-worked.
Added a couple of runq entry helper functions - one that malloc's a new
entry and fills it in with sensible defaults and another that adds and
runs a seqencue of entries.

- Break out the support for the XMAC II's PHY into an miibus driver.
- Reorganize the probe/attach stuff using newbus. Each XMAC is now
attached to the parent GEnesis controller using newbus. This is
necessary since each XMAC must also have an attached miibus, and
the miibus read/write register routines need to be able to get
at the softc struct for each XMAC, not the one for the parent
controller. This allows me to get rid of the grotty code I added
for selecting the unit numbers for the ifnet interfaces: the unit
numbers are now derived from the newbus-assigned unit numbers,
which should track with the ifnet interface numbers. I think.
At the very least, there should never be any collisions.

One critical bugfix:
- Fix a race where it was possible to get out of synch with the log
messages from the controller, if the controller hung up for any
period of time (eg. while resetting a SCSI bus). This would result
in an endless string of console errors, bringing the machine to a
halt.
o Modify xe driver to use this.
There's still some issues with this code, so xe can't map the cis just

I've done this by having requests to allocate memory propigate up the

working well. Also initialize ptr in the tuple. As well as minor
reorg of memory allocation. Likely need to do similar things for I/O

kernel. Justin agress that there is no other reasonable alternative to
do automatic rescans on connect.
The problem is that when a new device attaches to a SIM (SCSI host
controller) we need to send a XPT_SCAN_BUS command to the SIM using
xpt_action. This requires however that there is a peripheral available
to take the command (otherwise xpt_done and later bomb). The RESCAN
ioctl uses the same periph.
This enables a USB mass storage drive to do an automatic rescan on
connection of the drive.
The automatic dropping of a CAM entry on disconnection was already
working (asynchronous event).
The next thing to do is find someone to commit a change to vpo to do the
same thing. Just port umass_cam_rescan and friends across to that
