some longstanding issues:
o pass the vap since it's now the "coin of the realm" and required
to do things like set initial tx parameters in private node
state for use prior to association
o pass the mac address as cards that maintain outboard station
tables require this to create an entry (e.g. in ibss mode)
o remove the node table reference, we only have one node table
and it's unlikely this will change so this is not needed to
find the com structure
Add support for the Apple USB Ethernet adapter.
Work around the "latch in at the first working PHY address hack",
that fails for this adapter because it returns 0xffff when reading
from lower PHY addresses. Also add more debugging printfs

o correct mapping of CCK rates to PLCP; was using nonstandard Ralink
values which just happened to also be used by Zydas (so went unnoticed)
o change ieee80211_plcp2rate api to take a phy type instead of a flag
that indicates ofdm/!ofdm
o update drivers to match (restore per-driver code to map rate->PLCP)

o add IEEE80211_C_STA capability to indicate sta mode is supported
(was previously assumed) and mark drivers as capable
o add ieee80211_opcap array to map an opmode to the equivalent capability bit
o move IEEE80211_C_OPMODE definition to where capabilities are defined so it's
clear it should be kept in sync (on future additions)
o check device capabilities in clone create before trying to create a vap;
this makes driver checks unneeded
o make error codes return on failed clone request unique
o temporarily add console printfs on clone request failures to aid in
debugging; these will move under DIAGNOSTIC or similar before release
- Limit grabbing the lock to SIOCSIFFLAGS.
- Move ieee80211_start_all() to SIOCSIFFLAGS.
- Remove SIOCSIFMEDIA as it is not useful.
- Limit ether_ioctl to only SIOCGIFADDR. SIOCSIFADDR and SIOCSIFMTU have no
affect as there is no input/output path in the vap parent. The vap code
will handle the reinit of the mac address changes.
- Split off ndis_ioctl_80211 as it was getting too different to wired devices.
This fixes a copyout while locked and a lock recursion.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.

I've taken a slightly different approach than is used with the ICH8 controllers
in that each controller is not identified individually (eg USB A, USB B, etc).
Instead I've given then same description to each one even though the device ID
differs. This can easily be changed if desired, or ICH8 (and any others using
that approach) can be made to work as this does.
work on architectures with a write-back cache as the PIO writes end up
in the cache which the sync(BUS_DMASYNC_POSTREAD) in usb_transfer_complete
then discards; compensate in the xfer methods that do PIO by pushing the
writes out of the cache before usb_transfer_complete is called.
This fixes USB on xscale and likely other places.

hangs (one at boot, one at shutdown) in recent machines. First, only try
to take ownership of the EHCI controller if the BIOS currently owns the
controller. On a HP DL160 G5, the machine hangs when we try to take
ownership. Second, don't bother trying to give up ownership of the
controller during shutdown. It's not strictly required and a Dell DCS S29
hangs on shutdown after the config write.
Both of these changes match the behavior of the Linux EHCI driver. I also
think both of these hangs are caused by bugs in the BIOS' SMM handler
causing it to get stuck in an infinite loop in SMM.

than rely on the lockmgr support [1]:
* bump the waiters only if the interlock is held
* let brelvp() return the waiters count
* rely on brelvp() instead than BUF_LOCKWAITERS() in order to check
for the waiters number
- Remove a namespace pollution introduced recently with lockmgr.h
including lock.h by including lock.h directly in the consumers and
making it mandatory for using lockmgr.
- Modify flags accepted by lockinit():
* introduce LK_NOPROFILE which disables lock profiling for the
specified lockmgr
* introduce LK_QUIET which disables ktr tracing for the specified
lockmgr [2]
* disallow LK_SLEEPFAIL and LK_NOWAIT to be passed there so that it
can only be used on a per-instance basis
- Remove BUF_LOCKWAITERS() and lockwaiters() as they are no longer
used
This patch breaks KPI so __FreBSD_version will be bumped and manpages
updated by further commits. Additively, 'struct buf' changes results in
a disturbed ABI also.
[2] Really, currently there is no ktr tracing in the lockmgr, but it
will be added soon.

With write-allocate cache we get into the following scenario:
1. data has been updated in the memory by the USB HC, but
2. D-cache holds an un-flushed value of it
3. when affected cache line is being replaced, the old (un-flushed) value is
flushed and overwrites the newly arrived
This is possible due to how write-allocate works with virtual caches (ARM for
example).
In case of USB transfers it leads to fatal tags discrepancies in umass(4)
operation, which look like the following:
umass0: Invalid CSW: tag 1 should be 2
(probe0:umass-sim0:0:0:0): Request completed with CAM_REQ_CMP_ERR
(probe0:umass-sim0:0:0:0): Retrying Command

(probe0:umass-sim0:0:0:0): error 5
(probe0:umass-sim0:0:0:0): Retries Exausted
To eliminate this, a BUS_DMASYNC_PREREAD sync operation is required in
usbd_start_transfer().

- Include lock.h in lockmgr.h as nested header in order to safely use
LOCK_FILE and LOCK_LINE. As long as this code will be replaced soon
we can tollerate for a while this namespace pollution even if the real
fix would be to let lockmgr() depend by lock.h as a separate header.
