like other PCI network drivers. The sys/ofed directory is now mainly
reserved for generic infiniband code, with exception of the mthca driver.
- Add new manual page, mlx4en(4), describing how to configure and load
mlx4en.
- All relevant driver C-files are now prefixed mlx4, mlx4_en and
mlx4_ib respectivly to avoid object filename collisions when compiling
the kernel. This also fixes an issue with proper dependency file
generation for the C-files in question.
- Device mlxen is now device mlx4en and depends on device mlx4, see
mlx4en(4). Only the network device name remains unchanged.
- The mlx4 and mlx4en modules are now built by default on i386 and
amd64 targets. Only building the mlx4ib module depends on
WITH_OFED=YES .

- Replace tunables-only hw.psm.synaptics_support, hw.psm.trackpoint_support,
and hw.psm.elantech_support with respective sysctls declared with
CTLFLAG_TUN. It simplifies checking them in userland, also makes them
easier to get discovered by user
- Get rid of debug.psm.loglevel and hw.psm.tap_enabled TUNABLE_INT
declaration by adding CTLFLAG_TUN to read/write sysctls that were
already declared for these tunables.

Summary:
NXP/Freescale, among others, includes an optional cell-index property
on nodes to denote the SoC block number of the node. This can be useful if, for
example, a node is disabled or nonexistent in the fdt, or the blocks are not
organized in address-sorted order. For instance, on the P1022, DMA2 is located
at CCSR offset 0xC000, while DMA1 is located at 0x21000.

- The original 'disengage' ATA controller model does not work properly
for all possible disk configurations. Use the newly added ATA disk
veto eventhandler to fit into all possible disk configuration.
- If the 'invalid LUN' happens on blkvsc controllers, return
CAM_DEV_NOT_THERE so that CAM will not destroy attached disks under
the blkvsc controllers.

Suspend:
- Prevent the backend from being touched on TX path.
- Clear the RNDIS RX filter, and wait for RX to drain.
- Make sure that NVS see the chimney sending buffer and RXBUF
disconnection, before unlink these buffers from the channel.
Resume:
- Reconfigure the RNDIS filter.
- Allow TX path to work on the backend.
- Kick start the TX eof task, in case the OACTIVE is set.
This fixes various panics, when the interface has traffic and MTU
is being changed.

Elantech trackpads are found in some laptops like the Asus UX31E. They
are "synaptics compatible" but use a slightly different protocol.
Elantech hardware support is not enabled by default and just like
Synaptic or TrackPoint devices it should be enabled by setting
tunable, in this case hw.psm.elantech_support, to non-zero value

'compat' can never be NULL, because the compatible check loop ends when
compat->ocd_str is NULL. This causes ds1307 to attach to any unclaimed i2c
device.
- Added bhnd(4) bus APIs for per-core ioctl/iost register access.
- Updated reset/suspend bhnd(4) APIs for compatibility with ioctl/iost
changes.
- Implemented core reset/suspend support for both bcma(4) and siba(4).
- Implemented explicit release of all outstanding PMU requests at the bus
level when putting a core into reset.

* Don't do the antenna switching when setting up the rate table - we don't
take into account whether it's an active antenna or not (eg shared with BT.)
I'll look into this a bit more later.
* The default antenna is still 1, I'll look into that a bit more later.
(So no, this doesn't fix it for Larry who needs ANT_B to be active, not
ANT_A.)
* My changes to the rate control setup used the wrong method for finding
a suitable rate, which led to 1M CCK frames being queued for 11a operation.
This is .. sub-optimal. Change the rate control lookup path to use
the global table instead of the per-node table, which won't be setup
until the node rate table is setup (which happens way too late in this
game.)
Tested:
* Intel 7260, 2G and 5G operation.

AMD chipsets have proprietary mechanisms for dicovering resources.
Those resources are not discoverable via plug-and-play mechanisms
like PCI configuration registers or ACPI.
For this reason a chipset-specific knowledge of proprietary registers
is required.
At present there are two FreeBSD drivers that require the proprietary
resource discovery. One is amdsbwd which is a driver for the watchdog
timer in the AMD chipsets. The other is intpm SMBus driver when it
attaches to the newer AMD chipsets where the resources of the SMBus HBA
are not described in the regular PCI way.
In both cases the resources are discovered by accessing AMD PMIO space.
Thus, many definitions are shared between the two drivers.
This change puts those defintions into a common header file.
As an added benefit, intpm driver now supports newest FCHs built into
AMD processors of Family 15h, models 70h-7Fh and Family 16h, models
30h-3Fh.
