time_pps_fetch() to be used in blocking mode.
Also, don't init the pps api for system devices (consoles) that provide a
custom attach routine. The device may actually be a keyboard or other non-
tty device. If it wants to do pps processing (unlikely) it must handle
everything for itself. (In reality, only a sun keyboard uses a custom
attach routine, and it doesn't make a good pps device.)
For some reason 32-bit PIO writes are not working on 6Gbit/s Intel SATA
ports, while 16/32-bit PIO reads and 16-bit PIO writes are working fine.
3Gbit/s ports on the same controllers have no this problem.
Workaround this by disabling 32-bit PIO for all Intel controllers that may
have 6Gbit/s ports. It halves PIO performance from 6MB/s to 3MB/s, but
who bother about speed of such rare and slow mode, which is also highly
discouraged by SATA specifications?

There are still several bugs, but I've been using it for a while now.
Thanks to all the testers and to Adrian for his help with this
driver.
This driver isn't connected to the build yet, but it will be soon.
There's no MFC planned because the driver isn't very stable yet.

The initial commit broke a variety of debug and features that aren't
in the GENERIC kernels but are enabled in other platforms.
Main problem there was PIO mode support, that required KVA mapping.
Handle that case using recently added pmap_quick_enter_page(9) KPI,
mapping data pages to KVA one at a time.
with the net80211 stack.
Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.
Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:
- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
driver about any changes: number of wlan(4) interfaces, number of them
in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
driver experiences errors and can not attribute them to any specific
interface, driver updates ic_oerrors or ic_ierrors counters.
Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
now provided by net.wlan.devices sysctl.
Most drivers in this change were converted by me, except of wpi(4),
that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing
changes to at least 8 drivers. Thanks to Olivier Cochard, gjb@, mmoll@,
op@ and lev@, who also participated in testing. Details here:
https://wiki.freebsd.org/projects/ifnet/net80211
Still, drivers: ndis, wtap, mwl, ipw, bwn, wi, upgt, uath were not
tested. Changes to mwl, ipw, bwn, wi, upgt are trivial and chances
of problems are low. The wtap wasn't compilable even before this change.
But the ndis driver is complex, and it is likely to be broken with this
commit. Help with testing and debugging it is appreciated.

The ftdi chip itself has a "get bitmode" command that doesn't actually
return the current bitmode, just a snapshot of the gpio lines. The chip
apparently has no way to provide the current bitmode.
This implements the functionality at the driver level. The driver starts
out assuming the chip is in UART mode (which it will be, coming out of
reset) and keeps track of every successful set-bitmode operation so that
it can always return the current mode with UFTDIIOC_GET_BITMODE.

the blkfront driver to perform I/Os of up to 2 MB, subject to support from
the blkback to which it is connected and the initiation of such large I/Os
by the rest of the kernel. In practice, the I/O size is increased from 40 kB
to 128 kB.
The changes to xen/interface/io/blkif.h consist merely of merging updates
from the upstream Xen repository.
In dev/xen/blkfront/block.h we add some convenience macros and structure
fields used for indirect-page I/Os: The device records its negotiated limit
on the number of indirect pages used, while each I/O command structure gains
permanently allocated page(s) for indirect page references and the Xen grant
references for those pages.
In dev/xen/blkfront/blkfront.c we now check in xbd_queue_cb whether a request
is small enough to handle without an indirection page, and either follow the
previous behaviour or use new code for issuing an indirect segment I/O. In
xbd_connect we read the size of indirect segment I/Os supported by the backend
and select the maximum size we will use; then allocate the pages and Xen grant
references for each I/O command structure. In xbd_free those grants and pages
are released.
A new loader tunable, hw.xbd.xbd_enable_indirect, can be set to 0 in order to
disable this functionality; it works by pretending that the backend does not
support this feature. Some backends exhibit a loss of performance with large
I/Os, so users may wish to test with and without this functionality enabled.

variant of Microsoft RNDIS, i. e. their unofficial version of CDC ACM,

However, r275790 failed to put probing of RNDIS devices in question

- Initialize the device prior to querying it, as required by the RNDIS
specification. Otherwise already determining the MAC address may fail

- On detach, halt the device again.
- Use UCDC_SEND_ENCAPSULATED_{COMMAND,RESPONSE}. While these macros are
resolving to the same values as UR_{CLEAR_FEATURE,GET_STATUS}, the
former set is way more appropriate in this context.
- Report unknown - rather: unimplemented - events unconditionally and
not just in debug mode. This ensures that we'll get some hint of what
is going wrong instead of the driver silently failing.
- Deal with the Microsoft ActiveSync requirement of using an input buffer
