luns) firmware for the Fibre Channel cards.
We used to assume that if we didn't download firmware, we couldn't know
what the firmware capability with respect to SCCLUNs is- and it's important
because the lun field changes in the request queue entry based upon which
firmware it is.
At any rate, we *do* get back firmware attributes in mailbox register 6
when we do ABOUT FIRMWARE for all 2200/2300 cards- and for 2100 cards
with at least 1.17.0 firmware. So- we now assume non-SCCLUN behaviour
for 2100 cards with firmware < 1.17.0- and we check the firmware attributes
for other cards (loaded firmware or not).
This also allows us to get rid of the crappy test of isp_maxluns > 16-
we simply can check firmware attributes for SCCLUN behaviour.
This required an 'oops' fix to the outgoing mailbox count field for
ABOUT FIRMWARE for FC cards.
Also- while here, hardwire firmware revisions for loaded code for SBus
cards. Apparently the 1.35 or 1.37 f/w we've been loading into isp1000
just doesn't report firmware revisions out to mailbox regs 1, 2 and 3
like everyone else. Grumble. Not that this fix hardly matters for FreeBSD.

A nsp chip does suspend I/O write by 512bytes burst write,
though the chip only has 48 bytes FIFO. The chip assert I/O WAIT
signal to PC-Card bus after the CPU writes more than 48 bytes to
the chip if the SCSI device does not respond immediately in supsend
I/O burst write. If the device does not respond for a while it might
cause PC-Card bus timeout.
The previous work around was to wait the request from SCSI device.
But there are some devices which request bytes for synchronous transfer
immediately. So current work aound is to fill 32bytes FIFO, wait for
FIFO empty and burst write 512-32 bytes for every 512 bytes block.

Briefly, the significant changes include:
* Way better resource management in pccbb, pccard and cardbus.
* pccard hot-removal now appears to work.
* support pre-fetchable memory in cardbus.
* update cardbus to support new pci bus interface functions.
* Fix CIS reading to no longer use rman_get_virtual().
What's not there, but in the works:
* pccard needs to do interrupt properly and not read the ISR on single
function cards.
* real resource management for pccard
* a complete implementation of CIS parsing
* need to look into how to correctly use mutex in pccbb
This is the first part of a two-part update to NEWCARD. Changes in this
commit are non-functional, and includes the following:
* indentation and other changes to meet style(9).
* other minor style consistancy changes
* addition of comments
* renaming of device_t variables to be consistant across all of NEWCARD.

aren't will be clobbered by the next commit.)

It appears that a number of PrismII card vendors seem to be doing the
same thing (that is, using the same PCI bridge chip) to support PCI,

prevent/workaround TX lockups in this driver. The secret seems to be to
not let the TX DMA queue become too full. If we have too many packets
in the queue, we should wait for them to drain a bit before trying to
queue more. This should prevent the lockup from occurring, and if it
does occur, there is special code in sf_start() to kick the NIC in the
head and get it going again.
Special thanks to Glen Neff for helping me test this fix.

bypass some extra anti-foot-shooting measures. Currently, its only
effect is to allow detaching a device while it's still open (e.g.,
mounted). This is useful for testing how the system reacts to a disk
suddenly going away, which can happen with some removeable media.
At this point, the force option is only checked on detach, so it
would've been possible to allow the option to be passed with the
MDIOCDETACH operation. This was not done to allow the possibility of
having the force flag influence other tests in the future, which may
not necessarily deal with detaching the device.
