9976156f12 kern cons: introduce infrastructure for console grabbing by kernel
At the moment grab and ungrab methods of all console drivers are no-ops.

Current intended meaning of the calls is that the kernel takes control of
console input.  In the future the semantics may be extended to mean that
the calling thread takes full ownership of the console (e.g. console
output from other threads could be suspended).

733b92779e Many updates to cxgbe(4)
- Device configuration via plain text config file.  Also able to operate
  when not attached to the chip as the master driver.

- Generic "work request" queue that serves as the base for both ctrl and
  ofld tx queues.

- Generic interrupt handler routine that can process any event on any
  kind of ingress queue (via a dispatch table).

- A couple of new driver ioctls.  cxgbetool can now install a firmware
  to the card ("loadfw" command) and can read the card's memory
  ("memdump" and "tcb" commands).

- Lots of assorted information within dev.t4nex.X.misc.*  This is
  primarily for debugging and won't show up in sysctl -a.

- Code to manage the L2 tables on the chip.

- Updates to cxgbe(4) man page to go with the tunables that have changed.

- Updates to the shared code in common/

- Updates to the driver-firmware interface (now at fw 1.4.16.0)

4473d4da67 Add the 11n chipset RF frontends to the linker set, even though they're not
attached this way.

The AR5212 based NICs have a variety of RF frontends, so there's a linker set
which the AR5212 attach routine calls. The same framework is used for the
AR5416 and later but as there's a fixed RF frontend for each 11n NIC, it
is just directly attached.

However in the case of compiling a cut down HAL (eg _just_ AR9130 WMAC support),
the linker set ends up being empty and this causes the compile to fail.

So this is just a workaround for that - it means those users who wish an 11n
only HAL can compile the 11n chipsets and RF frontend they need, and just
"ath_ar5212" for the AR5212/AR5416 common code, and it'll just work.

59aab5d20c Rework link state tracking and remove superfluous link UP/DOWN
messages.
 o Add check for actually resolved speed in miibus_statchg callback
   instead of blindly reprogramming BCE_EMAC_MODE register.  The
   callback may be called multiple times(e.g. link UP, link
   transition, auto-negotiate complete etc) while auto-negotiation
   is in progress.  All unresolved link state changes are ignored
   now and setting BCE_EMAC_MODE after link establishment is done
   once.
 o bce(4) is careful enough not to drive MII_TICK if driver got a
   valid link.  To detect lost link, bce(4) relied on link state
   change interrupt and if driver see the interrupt, it forced to
   drive MII_TICK by calling bce_tick() in interrupt handler.
   Because bce(4) generates multiple link state change interrupts
   while auto-negotiation is in progress, bce_tick() would be
   called multiple times and this resulted in generating multiple
   link UP/DOWN messages.
   With this change, bce_tick() is not called in interrupt handler
   anymore such that miibus_statchg callback handles link state
   changes with consistent manner.

fd33ce416e Part 2 of 2 New deltas for the 1G drivers.
There have still been intermittent problems with apparent TX
hangs for some customers. These have been problematic to reproduce
but I believe these changes will address them. Testing on a number
of fronts have been positive.

EM: there is an important 'chicken bit' fix for 82574 in the shared
code this is supported in the core here.
    - The TX path has been tightened up to improve performance. In
      particular UDP with jumbo frames was having problems, and the
      changes here have improved that.
    - OACTIVE has been used more carefully on the theory that some
      hangs may be due to a problem in this interaction
    - Problems with the RX init code, the "lazy" allocation and
      ring initialization has been found to cause problems in some
      newer client systems, and as it really is not that big a win
      (its not in a hot path) it seems best to remove it.
    - HWTSO was broken when VLAN HWTAGGING or HWFILTER is used, I
      found this was due to an error in setting up the descriptors
      in em_xmit.

IGB:
    - TX is also improved here. With multiqueue I realized its very
      important to handle OACTIVE only under the CORE lock so there
      are no races between the queues.
    - Flow Control handling was broken in a couple ways, I have changed
      and I hope improved that in this delta.
    - UDP also had a problem in the TX path here, it was change to
      improve that.
    - On some hardware, with the driver static, a weird stray interrupt
      seems to sometimes fire and cause a panic in the RX mbuf refresh
      code. This is addressed by setting interrupts late in the init
      path, and also to set all interrupts bits off at the start of that.

4dab5c3769 Part 1 of two parts, this is the shared code changes in
support of new deltas for both em and igb drivers.

Note that I am not able to track all the bugs fixed in
this code, I am a consumer of it as a component of my
core drivers. It is important to keep the FreeBSD drivers
up to date with it however.

One important note is there is a key fix for 82574 in this
update. Also, there are lots of white space changes, I am
not happy about them but have no control over it :)

5d384a0de9 Announce flow control ability to PHY driver and enable RX flow
control.  Controller does not automatically generate pause frames
based on number of available RX buffers so it's very hard to
know when driver should generate XON frame in time.  The only
mechanism driver can detect low number of RX buffer condition is
ET_INTR_RXRING0_LOW or ET_INTR_RXRING1_LOW interrupt.  This
interrupt is generated whenever controller notices the number of
available RX buffers are lower than pre-programmed value(
ET_RX_RING0_MINCNT and ET_RX_RING1_MINCNT register).  This scheme
does not provide a way to detect when controller sees enough number
of RX buffers again such that efficient generation of XON/XOFF
frame is not easy.

While here, add more flow control related register definition.

fa1483dd2f Do not disable interrupt without knowing whether the raised
interrupt is ours.  Note, interrupts are automatically ACKed when
the status register is read.
Add RX/TX DMA error to interrupt handler and do full controller
reset if driver happen to encounter these errors.  There is no way
to recover from these DMA errors without controller reset.
Rename local variable name intrs with status to enhance
readability.

While I'm here, rename ET_INTR_TXEOF and ET_INTR_RXEOF to
ET_INTR_TXDMA and ET_INTR_RXDMA respectively.  These interrupts
indicate that a frame is successfully DMAed to controller's
internal FIFO and they have nothing to do with EOF(end of frame).
Driver does not need to wait actual end of TX/RX of a frame(e.g.
no need to wait the end signal of TX which is generated when a
frame in TX FIFO is emptied by MAC).  Previous names were somewhat
confusing.

1f009e2f39 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.
 o Remove checking a link in et_tick() as this is done by
   miibus_statchg callback.
