This change fixes a couple of issues with OPAL IPMI driver and
implements a mechanism to detect timeouts and discard old messages left
in receive queue, to avoid old messages from being confused with the
reply of new ones.

Previously they included sys/dev/cx/machdep.h, but the cx driver was
retired in r359178. These drivers haven't had real development for
a decade or more so there's no real benefit in sharing this file; just
copy it to the ce and cp subdirs.
The devices supported by these drivers are obsolete ISA cards, and the
sync serial protocols they supported are essentially obsolete too.

This reduces the lines bouncing around between the driver rx ithread and
the netmap rxsync thread. There is no net change in the size of the
struct (it continues to waste a lot of space).
This kind of split was originally proposed in D17869 by Marc De La
Gueronniere @ Verisign, Inc.

When vmx(4) was converted to an iflib driver in r343291, the
power-of-2 queue count constraint was removed as it appeared that
current implementations of the VMXNET3 virtual device no longer
required that constraint. It turns out that some of the
implementations still do, and on such systems, the device will fail to
initialize when configured with a non-power-of-2 RX or TX queue count.

These adjustments improve performance with jumbo frames and/or LRO
enabled (i.e., when there may be multiple descriptors per packet) by
increasing the default size of the receive queues and by always using
page-sized buffers for the body type receive ring.
This patch also adjust the initialization of the max frame size to
remove cases where certain configuration sequences would result in 2K
receive buffers being used instead of 4K ones when jumbo frames were
enabled.

This fixes a bug where the checksum offload status of received packets
was being taken from the first descriptor instead of the last, which
affected LRO packets.
The driver has been hardened against the device skipping receive
descriptors, although it is not believed that this can occur given the
way this implementation configures the receive rings.
Additionally, for packets received with the error indicator set, the
driver now forces the length of all fragments in that packet to zero
prior to passing it to iflib. Such packets should wind up being
discarded at some point in the stack anyway, but this removes any
questions by killing them in the driver.
Counters have been added (and exposed via sysctls) for skipped receive
descriptors, zero-length packets received, and packets received with
the error indicator set so that these conditions can be easily
observed in the field.

If the USB frame length is set to 1024 bytes, WMT_BSIZE, the EETI controller
will pack multiple touch events in the packet and the current code will only
process the first touch event.
As a result some important events are lost like releasing the finger from the

When iicbus is attached as child of Designware I2C controller it scans all
ACPI nodes for "I2C Serial Bus Connection Resource Descriptor" described
in section 19.6.57 of ACPI specs.
If such a descriptor is found, I2C child is added to iicbus, it's I2C
address, IRQ resource and ACPI handle are added to ivars. Existing
ACPI bus-hosted child is deleted afterwards.
The driver also installs so called "I2C address space handler" which is
disabled by default as nontested.
Set hw.iicbus.enable_acpi_space_handler loader tunable to 1 to enable it.

Without this change, if an AIF interrupt comes at the same time a SYNC
command is finished, the SYNC interrupt will be lost. This happens because
all interrupt bits (bellbits) are cleared, but only one of them is handled.
Debugging shows that, (at least) when !sc->msi_enabled and (sc->flags &
AAC_FLAGS_SYNC_MODE) is true (sync mode), both bits may be set at the same
time.
