6937a7ac6b Don't update if_obytes when transmitting packets. That is already done
in IFQ_HANDOFF() when the packet is passed to the start routine, so doing
it here resulted in double counting.

9f2d8a3834 Remove block reallocation used to make room for the cylinder group
summary structure.  From now on, when there is no room for it,
we simply allocate new one in a newly added cylinder group.

This patch removes a conditional in updcsloc(), reindents some code
there, and removes unused routines.  I decided to do it this way instead
of disabling reallocation when the filesystem is live and leaving it
as it is otherwise, because this allows for removal of lots of complicated
and hard to test code.  Also, conditionally disabling it would result
in a different layout in filesystems resized online and offline, which
would look somewhat weird.

3c0caf6ce6 Some code restructuring to bring the memory allocator out of netmap.c
and make it easier to replace it with a different implementation.
On passing, also fix indentation.

NOTE: I know that #include "foo.c" is ugly, but the alternative
(add another entry to sys/conf/files, add a separate header with
structs and prototypes, and expose functions that are meant to
be private) looks even worse to me.
We need a more modular way to specify dependencies and build options.

2dd9ea6f70 Add thread-private flag to indicate that error value is already placed
in td_errno. Flag is supposed to be used by syscalls returning
EJUSTRETURN because errno was already placed into the usermode frame
by a call to set_syscall_retval(9). Both ktrace and dtrace get errno
value from td_errno if the flag is set.

Use the flag to fix sigsuspend(2) error return ktrace records.

b6aeb1ab97 Only manipulate the PGA_EXECUTABLE flag on managed pages. This is a proxy
for whether the page is physical. On dense phys mem systems (32-bit),
VM_PHYS_TO_PAGE will not return NULL for device memory pages if device
memory is above physical memory even if there is no allocated vm_page.
Attempting to use the returned page could then cause either memory
corruption or a page fault.

8546e82467 Reapply r223198 which was reverted in the previous vendor import. Some
portions were already reapplied in r233708:
- Use a dedicated task to handle deferred transmits from the if_transmit
  method instead of reusing the existing per-queue interrupt task.
  Reusing the per-queue interrupt task could result in both an interrupt
  thread and the taskqueue thread trying to handle received packets on a
  single queue resulting in out-of-order packet processing.
- Call ether_ifdetach() earlier in igb_detach().
- Drain tasks and free taskqueues during igb_detach().

77b479e644 Allow device_busy() and device_unbusy() to be invoked while a device is
being attached.  This is implemented by adding a new DS_ATTACHING state
while a device's DEVICE_ATTACH() method is being invoked.  A driver is
required to not fail an attach of a busy device.  The device's state will
be promoted to DS_BUSY rather than DS_ACTIVE() if the device was marked
busy during DEVICE_ATTACH().

c85cb1a0a2 A couple of changes related to ixgbe operation in netmap mode:
- add a sysctl, dev.netmap.ix_crcstrip, to control whether ixgbe should
  strip the CRC on received frames. Defaults to 0, which keeps the CRC.
  and improves performance when receiving min-sized (64-byte) frames.
  This matters because  min-sized frames is one of the standard
  benchmarks for switches and routers, some chipsets seem to issue
  read-modify-write cycles for PCIe transactions that are not a
  full cache line, and a min-sized frame triggers the bug, resulting
  in reduced throughput -- 9.7 instead of 14.88 Mpps -- and heavy
  bus load.

- for the time being, always look for incoming packets on a select/poll
  even if there has not been an interrupt in the meantime. This is
  only a temporary workaround for a probable race condition in keeping
  track of rx interrupts.
  Add a couple of diagnostic vars to help studying the problem.

aa15c59eb1 Enable prefetching of descriptors on the TX ring, using the same
values as in the Intel driver 3.8.21 for linux.  The fact that it
is standard in the above driver suggests that it has no bad side
effects.

But of course there must be a reason for enabling features, not
just "it does not harm", so here it is a good one:

Prefetching enables full line rate even using a single queue (14.88
Mpps, compared to ~12 Mpps without prefetch).  This in turn is
terribly useful when one wants to schedule traffic.

For obvious reasons the difference is only visible with netmap
or other high speed solutions, but presumably the advantage
should be in the order of a fraction of a microsecond when
starting transmission on an empty queue.

Discussed with Jack Vogel.

019100de26 Back out r233646. Although it fixed most libgeom consumers under 32-bit
compatibility, it broke programs using devstat, under 32-bit compatibility and
not.

It's very difficult to fix the identifiers used by devstat, so this change is
simply being backed out.  Since changes to 3rd-party code seem likely, and may be
necessary to properly fix 32-bit binaries on 64-bit kernel, it would seem better
to make more invasive changes to fix GEOM's problems with 32-bit compatibility in
general.

The right thing to do is to replace all of the use of pointers as opaque
identifiers with a fixed-size (64-bit or even 32-bit should be enough for tracking
unique GEOM elments) field.  That probably maintains source compatibility with
most GEOM consumers, and allows xml2tree to make better assumptions about how to
decode the identifiers.
