finally we decided that it is time to break ABI and simply make if_baudrate
a 64-bit value. Meanwhile, the entire struct if_data was reviewed.
o Remove the if_baudrate_pf crutch.
o Make all fields of struct if_data fixed machine independent size. The
notion of data (packet counters, etc) are by no means MD. And it is a
bug that on amd64 we've got a 64-bit counters, while on i386 32-bit,
which at modern speeds overflow within a second.
This also removes quite a lot of COMPAT_FREEBSD32 code.
o Give 16 bit for the ifi_datalen field. This field was provided to
make future changes to if_data less ABI breaking. Unfortunately the
8 bit size of it had effectively limited sizeof if_data to 256 bytes.
o Give 32 bits to ifi_mtu and ifi_metric.
o Give 64 bits to the rest of fields, since they are counters.

private per-chip HAL.
This allows the ah_osdep.[ch] code to check whether the power state is
valid for doing chip programming.
It should be a no-op for normal driver work but it does require a
clean kernel/module rebuild, as the size of HAL structures have changed.
Now, this doesn't track whether the hardware is ACTUALLY awake,
as NETWORK_SLEEP wakes the chip up for a short period when traffic
is received. This doesn't actually set the power mode to AWAKE, so
we have to be careful about how we touch things.
But it's enough to start down the path of implementing station mode
chipset power savings, as a large part of the silliness is making
sure the chip is awake during periodic calibration / ANI and
random places where transmit may be occuring. I'd rather not a repeat
of debugging power save on ath9k, where races with calibration
and transmit path stuff took a couple years to shake out.

(pvid=1) and we already configure them to send to other ports.
Setting pvid=portnum would mean that there were separate vlangroups
for each ports, but 'leaking' into other ports. The result? All port
traffic flooded to all other port traffic.
Tested:
* DB120, AR9344 + AR8327 switch
The OpenWRT AR8xxx switch support flushes the ATU (address translation
unit) after each port link 'up' status change. I've modified this to
just flush on any port transition.
Whilst here, bump the number of ports on the AR8327 to 6, rather than
the default of 5. It's DB120 specific; I'll go and make this configurable
later.
There's some debugging code in here still; I am still debugging whether
this is or isn't working fully.
Tested:
* DB120, AR9344 + AR8327 switch
Obtained from: OpenWRT
This patch does four things:
* it globally disables mirroring;
* it globally sets the mirroring on each port to be disabled;
* the initial port setup now programs a portmask for the port to allow
transmission (forwarding) to all other ports bar itself;
* the vlan setup path now programs the portmask for the port to
allow transmission (forwarding) to all other ports bar itself.
Before this, I hard-coded the portmask to 0x3f which would mean all
ports (bar port 6, which currently isn't hooked up to anything.)
This means that traffic would be duplicated back out the port it
received it. I bet this wasn't .. optimal.
In any case, this _seems_ to make DHCP from my macosx laptop

to ensure it's actually working correctly on all my devices.

It turns out that there's a variant format of the RX statisitcs notification

I'll commit the statistics structure changes here - it's a no-op for the
driver. I'll later teach the driver code to populate a statistics structure
from the received message after reformatting things correctly.
I don't _think_ it's going to fix anything related to sensitivity programming
as the CCK/OFDM (non-11n) fields are in the same place for both formats.
But the HT structure and the general statistics aren't in the same place.

matching 'compatible' property. This probably has a short half-life (as
do most of the fdt_ functions), but it helps solve some near-term needs
until we work out the larger problems of device instantiation order
versus the order of things in the fdt data.
If the hardware is not in a good state (like maybe clocks aren't running
because of a configuration glitch) its timeout clock may also not work
correctly, and the next command sent will hang that thread forever. The
thread in question is usually the one and only thread (at init time) or
a bio queue worker thread whose lockup will eventually lead to the whole
system locking up when it runs out of buffers.
No sd card command should take longer than 250ms. This new code establishes
a 1-second timeout to allow plenty of safety margin over that.
Normally it never needs to wait here at all; waiting is done at the end
of the prior command. When doing a crash dump, the normal interrupt
mechanism isn't used; instead the interrupt handler is called repeatedly
in a polling-like manner. This can subvert hardware-specific drivers
and lead to trying to start a new command while the previous command is
still busy on the bus. Since the SD spec says the longest a card can
take to execute any command is 250ms, use that as a timeout.
