- 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.
which support a 2.5Gbps mode over fiber using next page extensions during
autonegotiation. Typically only found in blade systems which also include
a Broadcom 2.5Gbps capable switch.

oldthread should point at before we return.
- When cpu_switch() is called the td_lock pointer in the old thread may
point at the blocked lock. This prevents other processors from
switching into this thread while we're still switching out. Wait
until we're done deactivating the vmspace before we release the
thread by assigning to td_lock.
- Before we can activate the new vmspace we must make sure that the new
thread is not assigned to the blocked lock. It may be in the process
of switching out on another cpu. Spin until the new thread is
available.
- Use thread_lock() rather than sched_lock for per-thread scheduling
sychronization.
- Use the per-process spinlock rather than the sched_lock for per-process
scheduling synchronization.

- Add a new parameter to cpu_switch() that is used to release the lock on
the outgoing thread and properly acquire the lock on the incoming
thread. This parameter is not required for schedulers that don't do
per-cpu locking and architectures which do not support it may continue
to use the 4BSD scheduler. This feature is presently not supported
on ia64

- There is no globally visible scheduler lock any longer. For now the
watchdog can only check Giant. This model of checking particular locks
is flawed and should be revisited. Other metrics should be considered.

- Use sched_throw() rather than replicating the same cpu_throw() code for
each architecture. This also allows the scheduler to use any locking it
may want to.
- Use the thread_lock() rather than sched_lock when preempting.
- The scheduler lock is not required to synchronize release_aps.
