Now, it's safe to call the fwohci interrupt(polling) routine while ddb/gdb
is active. After this change, a dcons connnection over FireWire can survive
bus resets even in kernel debugger.
This means that it is not too late to plug a FireWire cable after a panic
to investigate the problem.
Actually there is a small window(between a jump to kernel from loader and
initialization of dcons_crom) in which no one can take care of a bus reset.
Except that window, firewire console should keep working
from loader to reboot even with a panic and a bus reset.
(as far as you enable LOADER_FIREWIRE_SUPPORT)
embedded storage in struct ucred. This allows audit state to be cached
with the thread, avoiding locking operations with each system call, and
makes it available in asynchronous execution contexts, such as deep in
the network stack or VFS.

cache size limit but this bucket row is empty. Normally we want to
recycle the oldest entry in the bucket row. If there isn't any the
TAILQ_REMOVE leads to a panic by trying to remove a non-existing
element. Fix this by just returning NULL and failing the insert.
This is not a problem as the TCP hostache is only advisory.

grab sched_lock. This would serialize calls to pmap_switch from
cpu_switch(). With the introduction of thread_lock, this is not
possible anymore, because thread_lock is not a single lock. It
varies. Secondly and most importantly, it's not needed at all. The
only requirement for pmap_switch() is that it's not preempted
while in the middle of updating the CPU and PCPU. In other words,
it's a critical region. No locking required.
This is enabled by default. It should be disabled for
those who are uneasy with peeking/poking from FireWire.
Please note sbp(4) and dcons(4) over FireWire need
this feature.
- Moved BCM5706S/5708S SerDes support to brgphy (since they are not technically
TBI interfaces)
- Added 2.5G support for BCM5708S
Comments:
Since this driver is shared with bge I tested several available controllers
supported by bge and all worked as expected, however the list was not
exhaustive. Need wider testing.

In Rx path it allocates a new mbuf with m_getcl(9) so the length of
the mbuf is MCLBYTES which is greater than a segment size specified by
the dma tag. This segment size mismatch caused a voluntary panic.
Fix the panic by settting the mbuf length to TULIP_DATA_PER_DESC.

- lock its own locks and drop Giant.
- create its own taskqueue thread.
- split interrupt routine
- use interrupt filter as a fast interrupt.
- run watchdog timer in taskqueue so that it should be
serialized with the bottom half.
- add extra sanity check for transaction labels.
disable ad-hoc workaround for unknown tlabels.
- add sleep/wakeup synchronization primitives
- don't reset OHCI in fwohci_stop()
when coping out association data.
- Fixes a small bug that prevented the SCTP_UNORDERED indication
from going up to the app on a recv in the sinfo_flags field.
seems not enough to verify its consistencies.
- Define AC97_MIXER_SIZE as SOUND_MIXER_NRDEVICES (25), since we
don't need more than that. Stop doing wild and random guess about
its size since we're stricly bound to it.
application specific SEND_OP_COND (CMD55 + ACMD41), go ahead and allow
100 tries. This gives a timeout of a second rather than the ~100ms
the old style produces.
I've had one old 16MB SD card which needs the extra time. I've now
had reports from the field that other cards need this too.

Add the machine-specific definitions for configuring the new physical
memory allocator.
Set the size of phys_avail[] and dump_avail[] using one of these
definitions.
