- Fix up TX speed changes.
- Make mpi-350 cards sort-of work with new firmware. It RXs okay but TXs
only work for about 14 packets then fails to get an interrupt. The
TX watchdog fires. It has been reported that my hack for now doesn't
break cards with the older firmware. It appears my card has lost
the ability to RX or TX at all but other peoples cards work. I assume
it got damaged in tansport.

Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma. At the moment, this is used for the
asynchronous busdma_swi and callback mechanism. Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg. dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create(). The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.
sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms. The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.
If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)
- Cache temp. keys so they are preserved across suspend/resume (MPI-350)
- Reads and writes are real fast to the MPI-350 causing early timeouts so

one RX & one TX buffer are used. Firmware support is not tested so for the
MPI-350 so it is disabled. Signal cache and monitor mode are not supported
yet. Signal cache is not supported since in encapsulation mode ethernet
frames are returned by the chip. LAN monitor mode support will be added
shortly. Thanks to Warner for the MPI-350 card he sent me.

general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

LEAP support is added, hints from Richard Johnson. I've verified this

Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep

Install header files in /usr/include/dev/an
Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol.
This way you can manage 2 keys a little easier. Map the home mode into
key 5. Enhance ifconfig to dump the various configured SSIDs. I use
a bunch of different ones and roam between them. Use the syntax similar
to the WEP keys to deal with setting difference SSIDs.
Bump up up the Card capabilities RID since they added 2 bytes to it
in the latest firmware. Thankfully we changed it from a terminal
failure so the card still worked but the driver whined.
