The existing code tries to use the beacon miss timer to signal that the AP
has gone away. Unfortunately this doesn't seem to be behaving itself.
I'll try to investigate why this is for the sake of completeness.
The result is the STA will stay "associated" to the AP it was associated
with when it suspended. It never receives a bmiss notification so it
never tries reassociating.

This includes adding support for skipping FTDI interfaces used for JTAG
leaving them for userland and just attaching to the RS232 half, similarly
to how the corresponding Linux drivers handles these kind of adapters.
While at it, sort uftdi_devs and return BUS_PROBE_SPECIFIC (because
uftdi_probe() alters the instance variables for better or worse as do
other probe routines of USB drivers) instead of 0.
- Remove duplicated entries for BeagleBone.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
- Remove some stray lines.

MAXPHYS should be based on PAGE_SIZE rather than SYM_CONF_DMA_BOUNDARY.
While at it, reuse the SYM_CONF_MAX_SG macro for specifying the maximum
number of DMA tags so sym(4) itself doesn't size memory beyond what's
required for handling MAXPHYS.

adding SRC_BASE and OSVERSION to match the new kernel, and putting

object, and eliminate the pread(2) call as well [1]. Mmap the first
page of the object temporaly, and unmap it on error or last use.
Potentially, this leaves one-page gap between succeeding dlopen(3),
but there are other mmap(2) consumers as well.
Fix several cases were the whole mapping of the object leaked on error.
Use MAP_PREFAULT_READ for mmap(2) calls which map real object pages [2].

* Resize some types. In particular, bfs_seqno can be uint16_t for now.
Previous work would assign the unassigned seqno a value of -1, which
I obviously can't do here.
* Remove bfs_pktdur. It was in the original code but nothing so far uses
it.
This gets ath_buf down (on my i386 system) to 292 bytes from 300 bytes.
I'd rather it be much, much smaller.

do some minor code shuffling of the FreeBSD /boot/loader metadata

caution.

Whilst I'm here, remove the warning about 802.11n being full of dragons.
It's nowhere near that scary now.

platform, which is where most of the code is from.

the boot parameters from initarm first thing. parse_boot_param parses
the boot arguments and converts them to the /boot/loader metadata the
rest of the kernel uses. parse_boot_param is a weak alias to
fake_preload_metadata, which all the platforms use now, but may become
more extensive in the future.
Since it is a weak symbol, specific boards may define their own
parse_boot_param to interface to custom boot loaders.

ath_start() is called.
This (defaults to 10 frames) gives for a little headway in the TX ath_buf
allocation, so buffer cloning is still possible.
This requires a lot omre experimenting and tuning.
It also doesn't stop a node/TID from consuming all of the available
ath_buf's, especially when the node is going through high packet loss
or only talking at a low TX rate. It also doesn't stop a paused TID
from taking all of the ath_bufs. I'll look at fixing that up in subsequent
commits.

indx will never be -1 on error, as none of dupfdopen(), finstall() and
kern_capwrap() modifies it on error, but what is more important none of
those functions install and leave file at indx descriptor on error.
Leave an assert to prove my words.

This saves us the filedesc lock/unlock cycle, fhold()/fdrop() cycle and closes
a race between finstall() and dupfdopen().
