This was off because the net80211 aggregation code was using the same
state pointers for both fast frames and ampdu tx support which led to some
pretty unfortunate panic-y behaviour.
Now that net80211 doesn't panic, let's flip this back on.
It doesn't (yet) do the horrific sounding thing of A-MPDU aggregates
of fast frames; that'll come next. It's a pre-requisite to supporting
AMSDU + AMPDU anyway, which actually speeds things up quite considerably
(think packing lots of little ACK frames into a single AMSDU.)
Tested:
* QCA955x SoC, AP mode
* AR5416, STA mode
* AR9170, STA mode (with local fast frame patches)
these functions are thin wrappers around calling the hardware-layer driver,
but some of them do sanity checks and return an error. Since the hardware
layer can only return IIC_Exxxxx status values, the iicbus helper functions
must also adhere to that, so that drivers at higher layers can assume that
any non-zero status value is an IIC_Exxxx value that provides details about
what happened at the hardware layer (sometimes those details are important
for certain slave drivers).
errno values that are at least vaguely equivelent. Also add a new status
value, IIC_ERESOURCE, to indicate a failure to acquire memory or other
required resources to complete a transaction.
The IIC_Exxxxxx values are supposed to communicate low-level details of the
i2c transaction status between the lowest-layer hardware driver and
higher-layer bus protocol and device drivers for slave devices on the bus.
Most of those slave drivers just return all status values from the lower
layers directly to their callers, resulting in crazy error reporting from a
user's point of view (things like timeouts being reported as "no such
process"). Now there's a helper function to make it easier to start
cleaning up all those drivers.
Make it clearer what each one means in the comments that define them.
IIC_BUSBSY was used in many places to mean two different things, either
"someone else has reserved the bus so you have to wait until they're done"
or "the signal level on the bus was not in the state I expected before/after
issuing some command".
Now IIC_BUSERR is used consistantly to refer to protocol/signaling errors,
and IIC_BUSBSY refers to ownership/reservation of the bus.
perform a stop operation on the bus if there was an error, otherwise the
bus will remain hung forever. Consistantly use 'if (error != 0)' style in
the function.
The current Xen console driver is crashing very quickly when using it on
an ARM guest. This is because the console lock is recursive and it may
lead to recursion on the tty lock and/or corrupt the ring pointer.
Furthermore, the console lock is not always taken where it should be and has
to be released too early because of the way the console has been designed.
Over the years, code has been modified to support various new features but
the driver has not been reworked.
This new driver has been rewritten with the idea of only having a small set
of specific function to write either via the shared ring or the hypercall
interface.
Note that HVM support has been left aside for now because it requires
additional features which are not yet supported. A follow-up patch will be
sent with HVM guest support.
List of items that may be good to have but not mandatory:
- Avoid to flush for each character written when using the tty
- Support multiple consoles

The fullmac firmware doesn't seem to populate a useful rssi indicator
in the RX descriptor, so if one plotted said values, they'd basically
look like garbage.
The reference driver implements a "get current rssi" firmware command
which I guess is really meant for station operation only (as hostap
operation would need rssi per station, not a single firmware read.)
So:
* populate sc_currssi during each calibration run;
* use this in the RX path instead of trying to reconstruct the RSSI
value and passing it around as a pointer;
* do up a quick hack to map the rssi hardware value to some useful
signal level;
* the survey results provide an RSSI value between 0..100, so just
do another quick hack to map it into some usefulish signal level;
* supply a faked noise floor - I haven't yet found how to pull it
out of the firmware.
The scan results and the station RSSI information is now more useful
for indicating signal strength / distance.
This logic is mostly crimed from the reference driver and the linux
r92su driver.
I verified that it (a) worked on the rsu hardware I have, and (b)
did traffic testing whilst watching what ath(4) sent as a hostap.
It successfully sent MCS8..15 rates (which requires 2-stream reception)
as well as MCS0..7 (which is 1-stream.)
Tested:

* .. which frees it upon NIC detach too;
* ensure urtwn_start() gets called after the completion of frame TX even if the
pending queue is empty, otherwise transmit will stall. It's highly unlikely that
the usb tx queue would be empty whilst the incoming send queue is full, but hey,
who knows.

Ensure that we re-queue starting transmit upon TX completion.
This solves two issues:
* It stops tx stalls - before this, if the transmit path filled the
mbuf queue then it'd never start another transmit.
* It enforces ordering - this is very required for 802.11n which
requires frames to be transmitted in the order they're queued.
Since everything remotely involved in USB has an unlock/thing/relock
pattern with that mutex, the only way to guarantee TX ordering is
to 100% defer it into a separate thread.
This now survives an iperf test and gets a reliable 30mbit/sec.
Correctly (I hope!) remove net80211 references before doing so.
Just doing a dumb mbufq drain isn't enough.
If enough traffic occurs and the mbuf queue fills up then transmit
stalls (which I'm not fixing in this commit!) but then the mbuf queue
stays full until the driver is removed. There's also the net80211
node refcounting leak.
This just ensures that during rsu_stop and detach the mbuf queue
is purged (and references!) so the queue-full situation can be
recovered from.

Ideally I'd just finish off the net80211 pluggable scan stuff and implement

connectivity interact with the net80211 stack.
Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.
Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:
- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
driver about any changes: number of wlan(4) interfaces, number of them
in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
driver experiences errors and can not attribute them to any specific
interface, driver updates ic_oerrors or ic_ierrors counters.
Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
now provided by net.wlan.devices sysctl.
