294ae9574d 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().

31bc0a8bff Fix error in r233949. Synchronizing icaches on uncacheable pages turns out
not to be a good idea, and of course the PV entry list for a page is never
empty after the page has been mapped.

8c1a6fb8e5 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.

b6c463eabc Support percent-encoded user and password
RFC 1738 specifies that any ":", "@", or "/" within a user name or
password in a URL is percent-encoded, to avoid ambiguity with the use
of those characters as URL component separators.

bef4cb5b9b 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.

1143c81c42 It is a logical error that in carp_multicast_cleanup()
we look at count of addresses on a particular vhid, we
should account number of addresses on cif.

To achieve this we need to run carp_attach() and

5ff92b1d9c Do not restore the register holding the TLS pointer when doing various
usermode context switches (long jumps and ucontext operations). If these
are used across threads, multiple threads can end up with the same TLS base.
Madness will then result.

This makes behavior on PPC match that on x86 systems and on Linux.

e1c6390e12 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.

a5766a62c7 * Since the API changed along the -CURRENT path (december 2011),
add a FreeBSD_version check.  It should work fine for compiling
  on -HEAD, 9.x and 8.x.

* Conditionally compile the 11n options only when 11n is enabled.

The above changes allow the ath(4) driver to compile and run on
8.1-RELEASE (Hi old PC-BSD!) but with the 11n stuff disabled.

I've done a test against the net80211 and tools in 8.1-RELEASE.
The NIC used in testing is the AR2427 in an EEEPC.

Just to be clear - this change is to allow the -HEAD ath/hal/rate
code to run on 9.x _and_ 8.x with no source changes. However,
when running on earlier kernels, it should only be used for legacy
mode. (Don't define ATH_ENABLE_11N.)
