5b9ee137aa Move to using filter for the change interrupts. Also rework the power
interrupt code to be more robust.  I've been running these changes for
over a year...  With these changes, I don't see the ath card going
into reset like the code in the tree.

9036240993 Fix a bug with the ael1006 PHY. The bug shows up as persistent but incomplete
packet loss, of between 10-30%. The fix is to put the PHY into
and take it out of local loopback mode when resetting the interface.

f37739d7ab Add support for newer JMC250/JMC260 revisions.
o Chip full mask revision 2 or later controllers have to
   set correct Tx MAC and Tx offload clock depending on negotiated
   link speed.
 o JMC260 chip full mask revision 2 has a silicon bug that can't
   handle 64bit DMA addressing. Add workaround to the bug by
   limiting DMA address space to be within 32bit.
 o Valid FIFO space of receive control and status register was
   changed on chip full mask revision 2 or later controllers. For
   these controllers, use default 16QW as it's supposed to be the
   safest value for maximum PCIe compatibility. JMicron confirmed
   performance will not be reduced even if the FIFO space is set
   to 16QW.
 o When interface is put into suspend/shutdown state, remove Tx MAC
   and Tx offload clock to save more power. We don't need Tx clock
   at all in this state.
 o Added new register definition for chip full mask revision 2 or
   later controllers.

Thanks to JMicron for their continuous support of FreeBSD.

2dd5c73163 Don't attempt to clear status updates if we did not do a link state
change.  As a side effect, this makes the excessive interrupts to

4b79449e2f Rather than using hidden includes (with cicular dependencies),
directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.

For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

c9c0c99f30 Bug fix from Chelsio which addresses the issue of the device resetting
when it sees only received packets.  In some cases where a device only
recieves data it mistakenly thinks that its transmitting side is broken
and resets the device.

bd4fa9d9e7 Add VLAN hardware tag insertion/stripping support. Tx/Rx checksum
offload for VLAN frames are also supported. The VLAN hardware
assistance is available only on 82550/82551 based controllers.
While I'm here change the confusing name of bit1 in byte 22 of
configuration block to vlan_drop_en. The bit controls whether
hardware strips VLAN tagged frame or not. Special thanks to wpaul
who sent valuable VLAN related information to me.

3364462355 Switch to ath hal source code. Note this removes the ath_hal
module; the ath module now brings in the hal support.  Kernel
config files are almost backwards compatible; supplying

device ath_hal

gives you the same chip support that the binary hal did but you
must also include

options AH_SUPPORT_AR5416

to enable the extended format descriptors used by 11n parts.
It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.

c1565b61d0 Major overhaul:
o eliminate private state indexed by 802.11 rate codes; use the hal's
  rate tables directly to get the same info
o calculate a mask of operational rates to optimize lookups and checks
  (instead of using for loops and similar)
o optimize size bin operations
o ignore rates marked as "do not use" in the hal phy tables
o fix bug that caused upshifting to break in 11g once the rate dropped
  below 11Mb/s
o add more intelligent multi-rate tx schedules
o add support for 1/2 and 1/4 width channels
o add dev.ath.X.sample_stats sysctl to dump runtime statistics to the console
  (needs to go up to a user app)
o export more tuning knobs via sysctls (still a couple of magic constants)

459bc4f0dd some of the 11n parts can hang under certain conditions without
necessary workarounds, add code to detect these hangs and distinguish
them from other events; note this code is only invoked for anomalous
conditions and (at the moment) is a noop because the hang detection
code is in a new hal that's coming shortly

0cfab8ddc1 - Add support for PMCs in Intel CPUs of Family 6, model 0xE (Core Solo
and Core Duo), models 0xF (Core2), model 0x17 (Core2Extreme) and
  model 0x1C (Atom).

  In these CPUs, the actual numbers, kinds and widths of PMCs present
  need to queried at run time.  Support for specific "architectural"
  events also needs to be queried at run time.

  Model 0xE CPUs support programmable PMCs, subsequent CPUs
  additionally support "fixed-function" counters.

- Use event names that are close to vendor documentation, taking in
  account that:
  - events with identical semantics on two or more CPUs in this family
    can have differing names in vendor documentation,
  - identical vendor event names may map to differing events across
    CPUs,
  - each type of CPU supports a different subset of measurable
    events.

  Fixed-function and programmable counters both use the same vendor
  names for events.  The use of a class name prefix ("iaf-" or
  "iap-" respectively) permits these to be distinguished.

- In libpmc, refactor pmc_name_of_event() into a public interface
  and an internal helper function, for use by log handling code.

- Minor code tweaks: staticize a global, freshen a few comments.
