unp_connect(): it is expected to return with the lock held, and two
possible error paths otherwise returned with it unlocked.
The fix committed here is slightly different from the patch in the
PR, but along an alternative line suggested in the PR.

since the the command and data that is being built to be sent to or read
from the HW lives in the softc. Commands are later run via an_setdef etc.
In the ioctl path various references are kept to the data stored in
the softc so it needs to be protected. Almost think of the command
in the softc a global variable since it essentially is. Since locking
wasn't done in this type of context the commands would get corrupted.
Thanks to avatar@ for catching some lock issues and dhw@ for testing.
Things are a lot more stable except for the MPI-350 cards. My an(4)
remote laptop stays on the network now.
The driver should be changed so that it uses private memory that is passed
to the functions that talk to the card. Then only those functions would
really need to grab locks.

drop the lock and then re-acquire it, revalidating TCP connection state
assumptions when we do so. This avoids a potential lock order reversal
(and potential deadlock, although none have been reported) due to the
inpcb lock being held over a page fault.

shortest possible chain of mbufs of m_defrag(9). What we want is
chains of mbufs that can be safely stored to a Tx descriptor which
can have up to STGE_MAXTXSEGS mbufs. The ethernet controller does
not need to align Tx buffers on 32bit boundary. So the use of
m_defrag(9) was waste of time.

option DIAGNOSTIC still disables inlining of certain pmap functions.)
Eliminate dead code from pmap_enter(). This code implemented an assertion.
On i386, an equivalent check is already implemented. However, on amd64,
a small change is required to implement an equivalent check.
Eliminate \n from a nearby panic string.
Use KASSERT() to reimplement pmap_copy()'s two assertions.

float_t was broken compatibly with FLT_EVAL_METHOD.
These definitions seem to be broken on powerpc and possibly on arm.
float_t is float on powerpc with gcc [-notraditional] according to
glibc, and FLT_EVAL_METHOD is marked with XXX on arm.

this in the core to be sure to handle other potential driver data.

- Track packet zone mbufs separately from other mbufs
- free packet zone buffers via m_free rather than trying to manage the refcount
as with clusters - its refcount and management seems to be "special"
but reread it from the device_t every time the device list is fetched.
Previously the device name in pciconf -l would not be updated when a driver
was unloaded or if a device was detached and attached to a different
driver.

hash type (hw.mxge.rss_hash_type).
Currently the driver defaults to using a single slice, so the default
behavior is unchanged. Also, transmit from non-zero slices is
disabled currently.

- Fix a bug introduced in 1.4.20 where speculative read by the processor in the
write-only doorbell region would cause a target-abort (as opposed to simply
returning random data). This could manifest itself as NMI or machine freeze
depending on how the BIOS/OS/chipset configuration handles target-abort.
- Add support for new revisions of -R cards (with AEL1002/AEL1010 xaui->xfi)
- Increase an internal timing (dispatch engine): fix possible spurious reset
(seen on very few cards).
lowest priority on the queue for the current cpu vs curthread's
priority. In the case that curthread is waking up many threads of a
lower priority as would happen with a turnstile_broadcast() or wakeup()
of many threads this prevents them from all ending up on the current cpu.
- In sched_add() make the relationship between a scheduled ithread and
the current cpu advisory rather than strict. Only give the ithread
affinity for the current cpu if it's actually being scheduled from
a hardware interrupt. This prevents it from migrating when it simply
blocks on a lock.

- add checks that pidx doesn't move pass cidx
- simplify mbuf free logic in collapse mbufs routine
