a slightly non-standard %S that's more useful in the UEFI environment,

* Add the new TX/RX frame formats;
* Use the right TX/RX format based on the frame info;
* Disable the 5xx firmware check, since now it should
somewhat work (but note, we don't yet use it unless
you manually add ucode11/initvals11 from the 5.x driver
to bwn-kmod-firmware;
* Misc: update some comments/debugging now I know what's
actually going on.
Tested:
* BCM4321MC, STA mode, both 4xx and 666 firmware, DMA mode
TODO:
* The newer firmware ends up logging "warn: firmware state (0)";
not sure yet what's going on there. But, yes, it still works.
I'm committing this via a BCM4321MC, 11a station, firmware

"iflib is a library to eliminate the need for frequently duplicated device
independent logic propagated (poorly) across many network drivers."
Participation is purely optional. The IFLIB kernel config option is
provided for drivers that want to transition between legacy and iflib
modes of operation. ixl and ixgbe driver conversions will be committed
shortly. We hope to see participation from the Broadcom and maybe
Chelsio drivers in the near future.

- Avoid a conditional branch on the return value of sleepq_resume_thread()
by ORing its return value into the boolean wakeup_swapper. This is
consistent with other sleepqueue functions which just pass this return
value to their caller.
- sleepq_resume_thread() unconditionally removes the thread from its queue,
so there's no need to maintain a pointer to the next element in the queue.

a string, interprets it as a standard UUID, and returns a binary from
of the UUID. uuid-to-string does the reverse. The binary UUID is in
allocated memory, so you'll need to free it with 'free' after you are
done using it. It won't be automatically garbage collected. Likewise
with the string...

* always allocate maximum size txhdr entries
* set the right rx header offset/framesize based on firmware
This still isn't what's completely required for fw 598 support; there's
more to come.

* Apple BCM94321MC 11abgn NIC, 11a STA mode, firmware version 4xx.

Previously the command completion interrupt would post any pending
command immediately before pcib_pcie_hotplug_update() had been
run to inspect the current status. Now, the command completion
interrupt merely clears the flag and stops the timer assuming that
the caller is always going to call pcib_pcie_hotplug_update() to
generate the next hotplug command if one is needed.
While here, fix a bug for systems with command completion where the
old (existing) value was written to the slot control register instead
of the new value. This fixes the complaint about a missing hotplug
interrupt on my T400.

devd requires location and pnpinfo strings generated by bus drivers
to be formatted as a list of name=value keypairs. Non-conforming
bus drivers cause devd to mis-parse device events for these buses.
Note that this documents the desired requirements. devctl_safe_quote()
doesn't yet escape backslash characters, and devd doesn't handle escaped
characters in quoted values.

The generation number is uint32_t so we can fit the complete range
of random(3). We could have used arc4random() but the result would
be unpredictable and it would prohibit reproducible builds.
While here add a comment where seeding is done: this affects
reproducible builds and might have to be re-visited to use a
release dependent value.

Speedup is hard to measure because the only time vdev_geom_open_by_guids
gets called on many drives at the same time is during boot. But with
vdev_geom_open hacked to always call vdev_geom_open_by_guids, operations
like "zpool create" speed up by 65%.

* Read all of a vdev's labels in parallel instead of sequentially.
* In vdev_geom_read_config, don't read the entire label, including
the uberblock. That's a waste of RAM. Just read the vdev config
nvlist. Reduces the IO and RAM involved with tasting from 1MB to
448KB.
