typically memory mapped bus, for example on the AMD Opteron A1100 the AHCI
device is mapped in the CPUs address space, and not through a PCI
controller.
Further work is needed for this to work with ACPI as this is expected to be
common on ARMv8 servers.

It seems the EEE made RX MAC enter LPI(Low Power Idle) mode such
that dwc(4) was not able to receive packets. Ideally dwc(4) should
be able to use EEE to save power during periods of low link
utilization(i.e. gating off clock). Due to lack of dwc(4)
datasheet it's not easy to take required steps for EEE on LPI
enter/exit events. Disabling EEE in PHY seems to be easy
workaround until dwc(4) supports EEE.
Updating EEE advertisement register on RTL8211F seems to have no
effect until reprogramming MII_ANAR, MII_100T2CR and MII_BMCR
with auto-negotiation. It's not clear whether it's related with
mii_phy_reset()'s BMCR_ISO handling for RTL8211F though.
It seems rgephy_reset() needs careful investigation for newer
RealTek PHYs.

Each virtual interface has its own MAC address, queues, and statistics.
The dedicated netmap interfaces (ncxgbeX / ncxlX) were already implemented
as additional VIs on each port. This change allows additional non-netmap
interfaces to be configured on each port. Additional virtual interfaces
use the naming scheme vcxgbeX or vcxlX.
Additional VIs are enabled by setting the hw.cxgbe.num_vis tunable to a
value greater than 1 before loading the cxgbe(4) or cxl(4) driver.
NB: The first VI on each port is the "main" interface (cxgbeX or cxlX).
T4/T5 NICs provide a limited number of MAC addresses for each physical port.
As a result, a maximum of six VIs can be configured on each port (including
the "main" interface and the netmap interface when netmap is enabled).
One user-visible result is that when netmap is enabled, packets received
or transmitted via the netmap interface are no longer counted in the stats
for the "main" interface, but are not accounted to the netmap interface.
The netmap interfaces now also have a new-bus device and export various
information sysctl nodes via dev.n(cxgbe|cxl).X.
The cxgbetool 'clearstats' command clears the stats for all VIs on the
specified port along with the port's stats. There is currently no way to
clear the stats of an individual VI.

After an MC reboot, a VF driver may reset before the PF driver has
finished bringing everything back up. This includes the VFs EVB port.
MC_CMD_VADAPTOR_ALLOC is the first MCDI call after an MC reboot to
require the EVB port, so if it fails with MC_CMD_ERR_NO_EVB_PORT,
retry the command a few times after waiting a while.

IPv4/IPv6 checksum offloading and VLAN tag insertion/stripping.
Since uether doesn't provide a way to announce driver specific offload
capabilities to upper stack, checksum offloading support needs more work
and will be done in the future.
Special thanks to Hayes Wang from RealTek who gave input.
tested on the Broadwell-Xeon with a hacked up version of pmcstudy -T. I still need
to circle back and add in to pmcstudy all the new tests from the Broadwell Vtune
guide (for the hacked up version I just made it so I could run the -T option). The
Skylake CPU is not yet available (even though Intel is advertising it .. imagine that).
The Skylake PMC's will need to be tested once we can get a sample skylake CPU :-)

The synth programming here requires the real centre frequency,
which for HT20 channels is the normal channel, but HT40 is
/not/ the primary channel. Everything else was using 'freq',
which is the correct centre frequency, but the hornet config
was using 'ichan' to do the lookup which was also the primary
channel.
So, modify the HAL call that does the mapping to take a frequency
in MHz and return the channel number.
Tested:
* Carambola 2, AR9331, tested both HT/20 and HT/40 operation.
On ARM, we must ensure proper interdevice write ordering.
The AHCI interrupt status register must be updated in HW before
registers in interrupt controller.
Unfortunately, only way how we can do it is readback.

Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).
This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.

Dynamic config partitions on boards that support RFID are divided into
a number of segments, each formatted like a partition, with header,
trailer and end tags. The first segment is the current active
configuration.
The segments are initialised by manftest and each contain a different
configuration e.g. firmware variant. The firmware can be instructed
via RFID to copy a segment over the first segment, hence changing the
active configuration. This allows ops to change the configuration of
a board prior to shipment using RFID.
Changes to the dynamic config may need to be written to all segments (in
particular firmware versions written by manftest) or just the first
segment (changes to the active configuration). See SF-111324-SW.
If only the first segment is written the code still needs to be aware of
the possible presence of subsequent segments as writing to a segment may
cause its size to increase, which would overwrite the subsequent
segments and invalidate them.
Boards that do not support RFID will only have one segment in their
dynamic config partition.

Adjust external port mapping table to distinguish Pavia from Monza.
Now the presence of any 40G mode implies at least 2 outputs per
external port. So Pavia 4x10G ports are now mapped to 1,2,3,4;
Monza 4x10G ports map to 1,1,2,2 as before.

- Make scan aborted by event restart immediately and infinitely.
- Improve handling of some loop events from firmware.
- Remove loop down timer, adding its functionality to scanner thread.
- Some more unification and simplification.
I added MYBEACON support a while ago to listen to beacons that are only
for your configured BSSID. For AR9380 and later NICs this results in
a lot less chip wakeups in station mode as it then only shows you beacons
that are destined to you.
However in IBSS mode you really do want to hear all beacons so you can do
IBSS merges. Oops.
So only use MYBEACON for STA + not-scanning, and just use BEACON for
the other modes it used to use BEACON for.
This doesn't completely fix IBSS merges though - there are still some
conditions to chase down and fix.
And expose vm_memattr_t of current mapping to consumers (as well as the
ability to change it to one of UC, WB, WC).
