When extracting the VLAN tag from if_em and if_lem receive descriptor
rings, copy the whole VLAN tag, not just the VLAN ID.  This fixes a
problem in which VLAN priority information was dropped when using
offloaded VLAN processing with these drivers.

Correct reporting of missing leaf vdevs so that the GUID required to
perform pool actions is always displayed.

cddl/contrib/opensolaris/cmd/zpool/zpool_main.c:
	The "zpool status" command reports the "last seen at"
	device node path when the vdev name is being reported
	by GUID.  Augment this code to assume a GUID is reported
	when a device goes missing after initial boot in addition
	to the previous behavior of doing this for devices that
	aren't seen at boot.

	In zpool_vdev_name(), report recently missing devices
	by GUID.  There is no guarantee they will return at
	their previous location.

Remove the assertion from tcp_input() that rcv_nxt is always greater
than or equal to rcv_adv and fix tcp_twstart() to handle this case by
assuming the last window was zero rather than a negative value.

The code in tcp_input() already safely handled this case.  It can happen
due to delayed ACKs along with a remote sender that sends data beyond
the window we previously advertised.  If we have room in our socket buffer
for the extra data beyond the advertised window, we will accept it.
However, if the ACK for that segment is delayed, then we will not
effectively fixup rcv_adv to account for that extra data until the
next segment arrives and forces out an ACK.  When that next segment
arrives, rcv_nxt will be beyond rcv_adv.

Import the first cut of "bsdbox".

This uses the existing crunchgen infrastructure to build
a series of tools designed to replace the base and networking
tools on an embedded system.

It reuses 'bsd.crunchgen.mk' to drive the actual file
creation. The rescue build system also uses this.

Unlike busybox, it doesn't include its own source - instead,
it just builds from the sources in /usr/src/ and leverages
the existing BSD framework.

Thie is still quite messy and could do with a whole lot of
cleaning up.   However it is proving to be very useful with
my current build framework, allowing me to build binary root
images that are about 30% less than simply cherrypicking files
and libraries from an installworld.

r222004 changed sbuf_finish() to not clear the buffer error status. As a
consequence sbuf_len() will return -1 for buffers which had the error
status set prior to sbuf_finish() call. This causes a problem in
pfs_read() which purposely uses a fixed size sbuf to discard bytes which
are not needed to fulfill the read request.

Work around the problem by using the full buffer length when
sbuf_finish() indicates an overflow. An overflowed sbuf with fixed size
is always full.

Last attempt at <tgmath.h>: do enable the new code for C11 compilers.

I was thinking by myself, if the new code doesn't work with GCC 4.2, why
not simply turn it into an efficient version for C11 compilers? By
changing the code to use _Generic() directly in that case, I can build
the tgmath regression test in a matter of milliseconds with Clang,
instead of the 8 seconds it used to take.

So by the time C11 becomes the default, it will pick up the new code
automatically. And now I will refrain from making more changes to
<tgmath.h>.

MFC r228325:
  Overhaul bus_dma(9) usage in et(4) and clean up TX/RX path.  This
  change should make et(4) work on any architectures.
   o Remove m_getl inline function and replace it with stanard mbuf
     interfaces.  Previous code tried to minimize code duplication
     but this came from incorrect use of common DMA tag.
     Driver may be still use a common RX allocation handler with
     additional structure changes but I don't see much point to do
     that it would make it hard to understand the code.
   o Remove DragonflyBSD specific constant EVL_ENCAPLEN, use
     ETHER_VLAN_ENCAP_LEN instead.
   o Add bunch of new RX status definition.  It seems controller
     supports RX checksum offloading but I was not able to make the
     feature work yet.  Currently driver checks whether recevied
     frame is good one or not.
   o Avoid a typedef ending in '_t' as style(9) says.
   o Controller has no restriction on DMA address space, so there
     is no reason to limit the DMA address to 32bit.  Descriptor
     rings,  status blocks and TX/RX buffers now use full 64bit DMA
     addressing.
   o Allocate DMA memory shared between host and controller as
     coherent.
   o Create 3 separate DMA tags to be used as TX, mini RX ring and
     stanard RX ring.  Previously it created a single DMA tag and it
     was used to all three rings.
   o et(4) does not support jumbo frame at this moment and I still
     don't quite understand how jumbo frame works on this controller
     so use two RX rings to handle small sized frame and normal sized
     frame respectively.  The mini RX ring will be used to receive
     frames that are less than or equal to 127 bytes.  The second RX
     ring is used to receive frames that are not handled by the first
     RX ring.
     If jumbo frame support is implemented, driver may have to choose
     better RX scheme by letting the second RX ring handle jumbo
     frames.  This scheme will mimic Broadcom's efficient jumbo frame
     handling feature.  However RAM buffer size(16KB) of the
     controller is too small to hold 2 jumbo frames, if 9KB
     jumbo frame is used, I'm not sure how good performance would it
     have.
   o In et_rxeof(), make sure to check whether controller received
     good frame or not.  Passing corrupted frame to upper layer is
     bad idea.
   o If driver receives a bad frame or driver fails to allocate RX
     buffer due to resource shortage condition, reuse previously
     loaded DMA map for RX buffer instead of unloading/loading RX
     buffer again.
   o et_init_tx_ring() never fails so change return type to void.
   o In watchdog handler, show TX DMA write back status of errored
     frame which could be used as a clue to debug watchdog timeout.
   o Add missing bus_dmamap_sync() in various places such that et(4)
     should work with bounce buffers(e.g. PAE).
   o TX side bus_dmamap_load_mbuf_sg(9) support.
   o RX side bus_dmamap_load_mbuf_sg(9) support.
   o Controller has no DMA alignment limit in RX buffer so use
     m_adj(9) in RX buffer allocation to make IP header align on 2
     bytes boundary.  Otherwise it would trigger unaligned access
     error in upper layer on strict alignment architectures.
     One of down side of controller is it provides limited set of RX
     buffer length like most Intel controllers.  This is not problem
     at this moment because driver does not support jumbo frame yet
     but it may require alignment fixup code to support jumbo frame
     on strict alignment architectures.
   o In et_txeof(), don't zero TX descriptors for transmitted frames.
     TX descriptors don't need write access after transmission.
     Driver sets IFF_DRV_OACTIVE when the number of available TX
     descriptors are less than or equal to ET_NSEG_SPARE.  Make sure
     to clear IFF_DRV_OACTIVE only when the number of available TX
     descriptor is greater than ET_NSEG_SPARE.

  Controller does not require TX start command for every frame.  So
  send a single TX command after setting up all TX frames.  This
  removes unnecessary register accesses and bus_dmamap_sync(9) calls.
  et(4) uses TX interrupt moderation so it's possible to have TX
  buffers that were already transmitted but waiting for TX completion
  interrupt.  If the number of available TX descriptor is less then
  1/3 of total TX descriptor, try reclaiming first to get enough free
  TX descriptors before setting up TX descriptors.
  After r228325, et_txeof() no longer tries to send frames after
  reclaiming TX buffers.  That change was made to give more chance
  to transmit frames in main interrupt handler since we can still
  send frames in interrupt handler with RX interrupt.  So right
  before exiting interrupt hander, after enabling interrupt, try to
  send more frames.  This gives slightly better performance numbers.

  While I'm here reduce number of spare TX descriptors from 8 to 4.
  Controller does not require reserved TX descriptors, it was just to
  reduce TX overhead.  After r228325, driver has much lower TX
  overhead so it does not make sense to reserve 8 TX descriptors.

r228327:
  Remove et_enable_intrs(), et_disable_intrs() functions and
  manipulation of interrupt register access is done through
  CSR_WRITE_4 macro.  Also add disabling interrupt into et_reset()
  because we want interrupt disabled state after controller reset.
  While I'm here slightly change interrupt handler to be more
  readable one.

r228331:
  Rework link state tracking and TX/RX MAC configuration.
   o Do not report link status if driver is not running.
   o TX/RX MAC configuration should be done with resolved speed,
     duplex and flow control after establishing a link so it can't
     be done in driver initialization routine.
     Move the configuration to miibus_statchg callback which will be
     called whenever any link state change is detected.
     At this moment, flow-control is not enabled yet mainly because
     I was not able to set correct flow control parameters to
     generate TX pause frames.
   o Now TX/RX MAC is enabled only when a valid link is detected.
     Rearragnge hardware initialization routine a bit to leave
     enabling MAC to miibus_statchg callback.  In order to that,
     TX/RX DMA engine is enabled in et_init_locked().
   o Introduce ET_FLAG_LINK flag to track current link state.
   o Introduce ET_FLAG_FASTETHER flag to mark whether controller is
     fast ethernet.  This flag is checked in miibus_statchg callback
     to know whether PHY established a valid link.
   o In et_stop(), TX/RX MAC is explicitly disabled instead of
     relying on et_reset().  And move et_reset() from et_stop() to
     controller initialization.  Controler reset is not required here
     and it would also clear critial registers(i.e station address,
     RX filter configuration, WOL etc) that are required to make WOL
     work.
   o Switching to current media is done in et_init_locked() after
     setting IFF_DRV_RUNNING flag.  This should ensure reliable
     auto-negotiation/manual link establishment.
   o In et_start_locked(), check whether driver got a valid link
     before trying to send frames.
