o add CFI_SUPPORT_STRATAFLASH compile option to enable support
o add new ioctls to get/set the factory and user/oem segments of the PR
and to get/set Protection Lock Register that fuses the user segment
o add #defines for bits in the status register
o update cfi_wait_ready to take an offset so it can be used to wait for
PR write completion and replace constants w/ symbolic names
Note: writing the user segment isn't correct; committing now to get review.

The TTY buffers used the standard <sys/queue.h> lists. Unfortunately
they have a big shortcoming. If you want to have a double linked list,
but no tail pointer, it's still not possible to obtain the previous
element in the list. Inside the buffers we don't need them. This is why
I switched to custom linked list macros. The macros will also keep track
of the amount of items in the list. Because it doesn't use a sentinel,
we can just initialize the queues with zero.
In its simplest form (the output queue), we will only keep two
references to blocks in the queue, namely the head of the list and the
last block in use. All free blocks are stored behind the last block in
use.
I noticed there was a very subtle bug in the previous code: in a very
uncommon corner case, it would uma_zfree() a block in the queue before
calling memcpy() to extract the data from the block.
for slave addressing by using left-adjusted slave addresses (i.e.
xxxxxxx0b).
- Require the low bit of the slave address to always be zero in smb(4) to
help catch broken applications.
- Adjust some code in the IPMI driver to not convert the slave address for
SSIF to a right-adjusted address. I (or possibly ambrisko@) added this in
the past to (unknowingly) work around the bug in ichsmb(4).

we, like TCP and UDP, move the checksum calculation
into the IP routines when there is no hardware support
we call into the normal SCTP checksum routine.
The next round of SCTP updates will use
this functionality. Of course the IGB driver needs
a few updates to support the new intel controller set
that actually does SCTP csum offload too.

device. The details include the current value of the BAR (including all
the flag bits and the current base address), its length, and whether or not
it is enabled. Since this operation is not invasive, non-root users are
allowed to use it (unlike manual config register access which requires
root). The intention is that userland apps (such as Xorg) will use this
interface rather than dangerously frobbing the BARs from userland to
obtain this information.
- Add a new sub-mode to the 'list' mode of pciconf. The -b flag when used
with -l will now list all the active BARs for each device.

Patches to make libusbhid and HID userland utilities compatible with
the new USB stack. All HID ioctls should go through the libusbhid
library to ensure compatibility. I have found at least one piece of
software in /usr/ports which needs to get updated before USB HID
devices will work. This is the X joystick input driver.

Move the interupt handler to a driver_intr_t type function as it was trying
to do way to much for a lightweight filter interrupt function.
Introduce much more locking around fc->mtx. Tested this for lock reversals
and other such lockups. Locking seems to be working better, but there
is much more to do with regard to locking. The most significant lock is
in the BUS RESET handler. It was possible, before this checkin, to set
a bus reset via "fwcontrol -r" and have the BUS RESET handler fire before
the code responsible for asserting BUS RESET was complete. This locking
fixes that issue.
Move some of the memory allocations in the fc struct to the attach function
in firewire.c
Rework the businfo.generation indicator to be merely a on/off bit now.
It's purpose according to spec is to notify the bus that the config ROM
has changed. That's it.
Catch and squash a possible panic in SBP where in the SBP_LOCK was held
during a possible error case. The error handling code would definitely
panic as it would try to acquire the SBP_LOCK on entrance.
Catch and squash a camcontrol/device lockup when firewire drives go away.
When a firewire device was powered off or disconnected from the firewire
bus, a "camcontrol rescan all" would hang trying to poll removed devices
as they were not properly detached. Don't do that.
