- The existing TCP INP_INFO lock continues to protect the global inpcb list
stability during full list traversal (e.g. tcp_pcblist()).
- A new INP_LIST lock protects inpcb list actual modifications (inp allocation
and free) and inpcb global counters.
It allows to use TCP INP_INFO_RLOCK lock in critical paths (e.g. tcp_input())
and INP_INFO_WLOCK only in occasional operations that walk all connections.

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.

enqueueing the frames when it fails. This way there is some latency
removed from the transmitting path.
- If IFF_DRV_OACTIVE is set (and also if IFF_DRV_RUNNING is not) just
enqueue the desired frames and return successful transmit. This way we
avoid to return errors on transmit side and resulting in
possible out-of-order frames. Please note that IFF_DRV_OACTIVE is set
everytime we get the threshold ring hit, so this can be happening quite
often.

On some platforms, the /cpus node contains cpu-to-cluster

causing incrementing of "id" variable and reporting more
CPUs available than it should.
To make "id" valid, increment it only when an entry really

xhci_start_controller() to xhci_init(). These values don't change at run-
time so there's no point of acquiring them on every USB_HW_POWER_RESUME
instead of only once during initialization. In r276717, reading the first
couple of registers in question already had been moved as a prerequisite
for the changes in that revision.
- Identify ASMedia ASM1042A controllers.
- Use NULL instead of 0 for pointers.

variant of Microsoft RNDIS, i. e. their unofficial version of CDC ACM,
has been disabled in r261544 for resolving a conflict with umodem(4).
Eventually, in r275790 that problem was dealt with in the right way.
However, r275790 failed to put probing of RNDIS devices in question
back.
- Initialize the device prior to querying it, as required by the RNDIS
specification. Otherwise already determining the MAC address may fail
rightfully.
- 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
the size of the expected reply or larger - except for variably sized
replies - when querying a device.
- Fix some pointless NULL checks, style bugs etc.
This changes allow urndis(4) to communicate with a Microsoft-certified
USB RNDIS test token.

uart_bus_attach() during its test that 20 iterations weren't sufficient
for clearing all pending interrupts, assuming this means that hardware
is broken and doesn't deassert interrupts. However, under pressure, 20
iterations also can be insufficient for clearing all pending interrupts,
leading to a panic as intr_event_handle() tries to schedule an interrupt
handler not registered. Solve this by introducing a flag that is set in
test mode and otherwise restores pre-r253161 behavior of uart_intr(). The
approach of additionally registering uart_intr() as handler as suggested
in PR 194979 is not taken as that in turn would abuse special pccard and
pccbb handling code of intr_event_handle(). [1]
- Const'ify uart_driver_name.
- Fix some minor style bugs.

- Use pointer assignment rather than a combination of pointers and
flags to switch buffers between unmapped and mapped. This eliminates
multiple flags and generally simplifies the logic.
- Eliminate b_saveaddr since it is only used with pager bufs which have
their b_data re-initialized on each allocation.
- Gather up some convenience routines in the buffer cache for
manipulating buf space and buf malloc space.
- Add an inline, buf_mapped(), to standardize checks around unmapped
buffers.

The NVMe specification has no ability to specify a maximum delete size
that is less than the full capacity of the namespace - so just using the
namespace size is the correct value here.
This fixes reported issues where ZFS trim on init looked like it was
hanging the system - previously the default I/O max size (128KB on
Intel NVMe controllers) was used for delete operations which worked out
to only about 8MB/s. With this patch I can add an 800GB DC P3700
drive to a ZFS pool in about 15-20 seconds.
