If the payload of an mbuf ends at a page boundary count_mbuf_nsegs would
incorrectly consider the next mbuf's payload physically contiguous based

The driver currently supports chips that are fully compliant with the
JEDEC SPD / EEPROM / TS standard (JEDEC Standard 21-C,
TSE2002 Specification, frequenlty referred to as JEDEC JC 42.4).
Additionally some chips from STMicroelectronics are supported as well.
They are compliant except for their Device ID pattern.
Given the continued lack of any common sensor infrastructure, the driver
uses an ad-hoc sysctl to report the temperature.

If the device tree doesn't contain a cpu-handle field in any bman-portal or
qman-portal, it will exit without setting up the devinfo, leaving it
uninitialized. This will lead to attempts to free random memory, and ultimately
panic.
Currently the network change is simulated by link status changes.

Instead replace it with a different hack, that turns fman into a simplebus
subclass, and maps its children within its address space.
Since all PHY communication is done through dtsec0's mdio space, the FDT
contains a reference to the dtsec0 mdio handle in all nodes that need it.
Instead of using Freescale's implementation for MII access, use our own (copied
loosely from the eTSEC driver, and could possibly be merged eventually). This
lets us access the registers directly rather than needing a full dtsec interface
just to access the registers.
Future directions will include turning fman into more of a simplebus, and not
mapping the region and playing games. This will require changes to the dtsec
driver to make it a child of fman, and possibly other drivers as well.
host-programmed DMA regions. This change seemingly fixes the
descriptor fetches, but the packet memory accesses are left
problematic.

fix build on 32 bit platforms
simplify logic in netmap_virt.h
The commands (in net/netmap.h) to configure communication with the
hypervisor may be revised soon.
At the moment they are unused so this will not be a change of API.
As part of an effort to extend Book-E to the 64-bit world, make the necessary
changes to the DPAA/dTSEC driver set to be integer-pointer conversion clean.
This means no more casts to int, and use uintptr_t where needed.
Since the NCSW source is effectively obsolete, direct changes to the source tree
are safe.
All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.
Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw
Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.
