o call firmware_put() early to release the firmware module
o on firmware panics or watchdog timeouts, schedule a task to reinitialize
the interface (we may sleep in iwi_init())
o discard oversized rx frames
flag isn't enough - the filter needs to be set up too, or no multicast frames

o stop processing interrupts after a firmware fatal error or a radio kill
o clarify the possible values for the 'antenna' sysctl.
o by default, let the firmware do antenna diversity.
the firmware will periodically switch to another antenna to evaluate the
signal quality.
ATA framework. Mainly written to be able to use USB Flash keys.
This is work in progress so use with care :)
Doesn't need CAM and cannot coexist with umass.c
table. Previously, the ddb code knew of each linker set of auxiliary
commands and which explicit command list they were tied to. These changes
add a simple command_table struct that contains both the static list of
commands and the pointers for any auxiliary linker set of additional
commands. This also makes it possible for other arbitrary command tables
to be defined in other parts of the kernel w/o having to edit ddb itself.
The DB_SET macro has also been trimmed down to just creating an entry in
a linker set. A new DB_FUNC macro does what the old DB_SET did which is
to not only add an entry to the linker set but also to include a function
prototype for the function being added. With these changes, it's now also
possible to create aliases for ddb functions using DB_SET() directly if
desired.

Get rid of the pccard front-end while I'm here since all adapters are
cardbus ones.

into a separate module. Accordingly, convert the option into a device
named similarly.
Note for MFC: Perhaps the option should stay in RELENG_6 for POLA reasons.

to call back for completition and something else is holding the taskqueue
waiting for ATA to return data.
This should clear up the "semaphore timeout !! DANGER Will Robinson !!"
in most situations, and log "taskqueue timeout - completing request directly"
instead, with a delayed "WARNING - freeing taskqueue zombie request" when
the taskqueue finally calls us back with the now stale request.
(It would have been nice if there was a way to remove a scheduled item from
a taskqueue, but that is not currently implemented in the kernel).
A real fix for this is in the works but wont make it to 6.1RELEASE
definite MFC candidate.
- Don't use a common buffer in the softc to store per-command data. Reserve
a buffer in the command itself.
- Don't allocate DMA memory for the kernel command structures when all you
really need is DMA memory for the scratch buffer embedded in them. Instead
allocate a slab for the scratch buffers and divide it up as needed.
- Call bus_dmamap_unload() at the completion of commands.
- Preserve and clear the CAM CCB status flags at completion.
- Reorder some low-level command operations to try to close races.
- Limit the simq to 32 commands for now. There are some serious problems
with the driver under load that are not well understood, so keeping the
simq lower helps avoid this. It has been tested at a higher value, but
this is a safe value that doesn't show much performance degredation.
These changes allow the driver to work reliably with >4GB of memory on i386
and amd64, and also work around deadlocks seen under very high load in
certain situations. The work-around is far from ideal, but without and
documentation it is hard to know what the right fix is.

By default syscons(4) will look for the kbdmux(4) keyboard first, and then,
if not found, look for any keyboard.
Current kbd code is modified so if kbdmux(4) is the current keyboard, all
new keyboards are automatically added to the kbdmux(4).
Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at
the loader prompt, or at runtime, by kldload'ing the kbdmux module and
releasing current active keyboard.
If, for whatever reason, kbdmux(4) is not required/desired then just do
not load it and everything should work as before. It is also possible to
kldunload kbdmux at runtime and syscons(4) will automatically switch to
the first available keyboard.

mpt_soft_reset more than once. And to wait for MPT_DB_STATE_READY
twice. I mean, this is crucial- give the IOC a chance to get
ready.
If mpt_reset is called to reinit things, and we succeed, make
sure to re-enable interrupts. This is what has mostly led to
system lockup after having to hard reset the chip. Also, if
we think that interrupts aren't function in mpt_cam_timeout,
for goodness sake, turn them on again.
In read_cfg_header, return distinguishing errnos so the caller
can decide what's an error. It's *not* an error to fail to
read a RAID page from a non-RAID capable device like the FC929X.
Some whitespace fixes (removing spaces from ends of lines).
