Add kern.racct.enable tunable and RACCT_DISABLED config option.
The point of this is to be able to add RACCT (with RACCT_DISABLED)
to GENERIC, to avoid having to rebuild the kernel to use rctl(8).

MFC r282901:

Build GENERIC with RACCT/RCTL support by default.  Note that it still
needs to be enabled by adding "kern.racct.enable=1" to /boot/loader.conf.

Note those two are MFC-ed together, because the latter one changes the
name of RACCT_DISABLED option to RACCT_DEFAULT_TO_DISABLED.  Should have
committed the renaming separately...

Overhaul if_gre(4).

  Split it into two modules: if_gre(4) for GRE encapsulation and
  if_me(4) for minimal encapsulation within IP.

  gre(4) changes:
  * convert to if_transmit;
  * rework locking: protect access to softc with rmlock,
    protect from concurrent ioctls with sx lock;
  * correct interface accounting for outgoing datagramms (count only payload size);
  * implement generic support for using IPv6 as delivery header;
  * make implementation conform to the RFC 2784 and partially to RFC 2890;
  * add support for GRE checksums - calculate for outgoing datagramms and check
    for inconming datagramms;
  * add support for sending sequence number in GRE header;
  * remove support of cached routes. This fixes problem, when gre(4) doesn't
    work at system startup. But this also removes support for having tunnels with
    the same addresses for inner and outer header.
  * deprecate support for various GREXXX ioctls, that doesn't used in FreeBSD.
    Use our standard ioctls for tunnels.

  me(4):
  * implementation conform to RFC 2004;
  * use if_transmit;
  * use the same locking model as gre(4);

r277637, and r283149 (by emaste@).

r276485 is the real change here, the rest deal with the fallout of
mp_ring's reliance on 64b atomics.

Use the incorrectly spelled 'eigth' from struct pkthdr in this branch
instead of MFC'ing r261733, which would have renamed the field of a
public structure in a -STABLE branch.
---

r276480:
Temporarily unplug cxgbe(4) from !amd64 builds.

r276485:
cxgbe(4): major tx rework.

a) Front load as much work as possible in if_transmit, before any driver
lock or software queue has to get involved.

b) Replace buf_ring with a brand new mp_ring (multiproducer ring).  This
is specifically for the tx multiqueue model where one of the if_transmit
producer threads becomes the consumer and other producers carry on as
usual.  mp_ring is implemented as standalone code and it should be
possible to use it in any driver with tx multiqueue.  It also has:
- the ability to enqueue/dequeue multiple items.  This might become
  significant if packet batching is ever implemented.
- an abdication mechanism to allow a thread to give up writing tx
  descriptors and have another if_transmit thread take over.  A thread
  that's writing tx descriptors can end up doing so for an unbounded
  time period if a) there are other if_transmit threads continuously
  feeding the sofware queue, and b) the chip keeps up with whatever the
  thread is throwing at it.
- accurate statistics about interesting events even when the stats come
  at the expense of additional branches/conditional code.

The NIC txq lock is uncontested on the fast path at this point.  I've
left it there for synchronization with the control events (interface
up/down, modload/unload).

c) Add support for "type 1" coalescing work request in the normal NIC tx
path.  This work request is optimized for frames with a single item in
the DMA gather list.  These are very common when forwarding packets.
Note that netmap tx in cxgbe already uses these "type 1" work requests.

d) Do not request automatic cidx updates every 32 descriptors.  Instead,
request updates via bits in individual work requests (still every 32
descriptors approximately).  Also, request an automatic final update
when the queue idles after activity.  This means NIC tx reclaim is still
performed lazily but it will catch up quickly as soon as the queue
idles.  This seems to be the best middle ground and I'll probably do
something similar for netmap tx as well.

e) Implement a faster tx path for WRQs (used by TOE tx and control
queues, _not_ by the normal NIC tx).  Allow work requests to be written
directly to the hardware descriptor ring if room is available.  I will
convert t4_tom and iw_cxgbe modules to this faster style gradually.

r276498:
cxgbe(4): remove buf_ring specific restriction on the txq size.

r277225:
Make cxgbe(4) buildable with the gcc in base.

r277226:
Allow cxgbe(4) to be built on i386.  Driver attach will succeed only on
a subset of i386 systems.

r277227:
Plug cxgbe(4) back into !powerpc && !arm builds, instead of building it
on amd64 only.

r277230:
Build cxgbe(4) on powerpc64 too.

r277637:
Make sure the compiler flag to get cxgbe(4) to compile with gcc is used
only when gcc is being used.  This is what r277225 should have been.

6e387585c4 Fix build issue and incompatibilites introduced by r283620.
- Re-introduce "device ixgbe" option for kernel configs. This allows
  users to continue using existing kernel configurations, while still
  letting if_ix and if_ixv exist to allow ifconfig magic to work.
  Though the amd64 GENERIC config has "device ix" and "device ixv" instead of
  "device ixgbe".

  This is achieved by making the if_ixgbe module a stub that depends
  on if_ix and if_ixv.

- Replace if_baudrate assignment with if_initbaudrate() call.

Thanks to jhb@ for the stub module suggestion and pointing out the if_baudrate
error.

Drop experimental ext2fs dir_index support.

The htree directory index is a highly desirable feature for research
purposes and was meant to improve performance in our ext2/3 driver.
Unfortunately our implementation has two problems:

- It never really delivered any performance improvement.
- It appears to corrupt the filesystem in undetermined circumstances.

Strictly speaking dir_index is not required for read/write support in
ext2/3 and our limited ext4 support still works fine without it.

Regain stability in the ext2 driver by removing it. We may need it back
(fixed) if we want to support encrypted ext4 support but thanks to the
wonders of version control we can always revert this change and bring it
back.

MFC support for PCI Alternate RID Interpretation.  ARI is an optional PCIe
feature that allows PCI devices to present up to 256 functions on a bus.
This is effectively a prerequisite for PCI SR-IOV support.

   Add a method to get the PCI RID for a device.

   Re-implement the DMAR I/O MMU code in terms of PCI RIDs

   Under the hood the VT-d spec is really implemented in terms of
   PCI RIDs instead of bus/slot/function, even though the spec makes
   pains to convert back to bus/slot/function in examples.  However
   working with bus/slot/function is not correct when PCI ARI is
   in use, so convert to using RIDs in most cases.  bus/slot/function
   will only be used when reporting errors to a user.

r264011:
   Add support for PCIe ARI

   PCIe Alternate RID Interpretation (ARI) is an optional feature that
   allows devices to have up to 256 different functions.  It is
   implemented by always setting the PCI slot number to 0 and
   re-purposing the 5 bits used to encode the slot number to instead
   contain the function number.  Combined with the original 3 bits
   allocated for the function number, this allows for 256 functions.

   This is enabled by default, but it's expected to be a no-op on currently
   supported hardware.  It's a prerequisite for supporting PCI SR-IOV, and
   I want the ARI support to go in early to help shake out any bugs in it.
   ARI can be disabled by setting the tunable hw.pci.enable_ari=0.
