MFC: r194763, r194886

- Initialize the ifnet structure, especially if_dname, before probing
  the PHYs as some PHY drivers use it (but probably shouldn't). How
  gem(4) has worked with brgphy(4) on powerpc without this so far is
  unclear to me.
- Call ether_ifdetach(9) before stopping the controller and the
  callouts. The consensus is that the latter is now safe to do and
  should also solve the problem of active BPF listeners clearing
  promiscuous mode can result in the tick callout being restarted
  which in turn will trigger a panic once it's actually gone.
- Introduce a dying flag which is set during detach and checked in
  gem_ioctl() in order to prevent active BPF listeners to clear
  promiscuous mode which may lead to the tick callout being restarted
  which will trigger a panic once it's actually gone.
- In gem_stop() reset rather than just disable the transmitter and
  receiver in order to ensure we're not unloading DMA maps still in
  use by the hardware. [1]
- The blanking time is specified in PCI clocks so we should use twice
  the value when operating at 66MHz.
- Spell some 2 as ETHER_ALIGN and a 19 as GEM_STATUS_TX_COMPLETION_SHFT
  to make the actual intentions clear.
- As we don't unload the peak attempts counter ignore its overflow
  interrupts.
- Remove a stale setting of a variable to GEM_TD_INTERRUPT_ME which
  isn't used afterwards.
- For optimum performance increment the TX kick register in multiples
  of 4 if possible as suggested by the documentation.
- Partially revert r164931; drivers should only clear the watchdog
  timer if all outstanding TX descriptors are done.
- Fix some debugging strings.
- Add a missing BUS_DMASYNC_POSTWRITE in gem_rint().
- As the error paths in the interrupt handler are generally unlikely
  predict them as false.
- Add support for the SBus version of the GEM controller. [2]
- Add some lock assertions.
- Improve some comments.
- Fix some more or less cosmetic issues in the code of the PCI front-end.

Add a MD __PCI_BAR_ZERO_VALID which denotes that BARs containing 0
actually specify valid bases that should be treated just as normal.
The PCI specifications have no indication that 0 would be a magic value
indicating a disabled BAR as commonly used on at least amd64 and i386
but not sparc64. It's unclear what to do in pci_delete_resource()
instead of writing 0 to a BAR though as there's no (other) way do
disable individual BARs so its decoding is left enabled in case of
__PCI_BAR_ZERO_VALID for now.

Improve mxge watchdog routine's ability to reliably reset a failed NIC:

- Mark the link as down, so if watchdog reset fails, link watching
    failover software can notice it
- Don't send MXGEFW_CMD_ETHERNET_DOWN if the NIC has been reset, it is
    not needed, and will fail on a freshly reset NIC.
- Ensure the transmit routines aren't attempting to PIO write to doorbells
    while the NIC is being reset.
- Download the correct f/w, rather than using the EEPROM f/w after reset.
- Export a count of the number of watchdog resets via sysctl
- Zero all f/w stats at reset.  This will lead to less confusing
    diagnostic output when investigating NIC failures.

Use an unsigned integer for storing the key code.

It seems Clang breaks when checking for SPCLKEY, which is now
0x80000000. Using an unsigned integer fixes this. This is also
consistent with other pieces of kbd/syscons code, because these also use
u_int.

- According to Linux, the ALi M5451 can do 31-bit DMA instead of just
  30-bit like the reset of the controllers supported by this driver.
  Actually ALi M5451 can be setup up to generate 32-bit addresses by
  setting the 31st bit via the accompanying ISA bridge, which allows
  it to work in sparc64 machines whose IOMMU require at least 32-bit
  DMA. Even though other architectures would also benefit from 32-bit
  DMA, enabling this bit is limited to sparc64 as bus_dma(9) doesn't
  generally guarantee that a low address of BUS_SPACE_MAXADDR_32BIT
  results in a buffer in the 32-bit range.
- According to Tatsuo YOKOGAWA's ali(4), the the DMA transfer size of
  ALi M5451 is fixed to 64k and in fact using the default size of 4k
- The 4DWAVE DX and NX require the recording buffer to be 8-byte
  aligned so adjust the bus_dma_tag_create(9) accordingly.
- Unlike the rest of the controllers supported by this driver, the
  ALi M5451 only has 32 hardware channels instead of 64 so limit the
  loop in tr_intr() accordingly. [1]

- Add missing bus_dmamap_sync(9) calls for the work DMA map. Previously
  the work area was totally unsynchronized which means this driver only
  had a chance of working on x86 when no bounce buffers were involved,
  which isn't that likely given that support for 64-bit DMA is currently
  broken throughout ata(4).
- Add necessary little-endian conversion of accesses to the work area,
  making this driver work on big-endian hosts. While at it, use the
  alignment-agnostic byte order encoders in order to be on the safe side.
- Clear the reserved member of the SG list entries in order to be on the
  safe side. [1]

rwlock implemented from libthr need to fall through the 'hard path' and
query umtx also if the shared waiters bit is set on a shared lock.
The writer starvation avoidance technique, infact, can lead to shared
waiters on a shared lock which can bring to a missed wakeup and thus
to a deadlock if the right bit is not checked (a notable case is the
writers counterpart to be handled through expired timeouts).

Fix that by checking for the shared waiters bit also when unlocking the
shared locks.

That bug was causing a reported MySQL deadlock.
Many thanks go to Nick Esborn and his employer DesertNet which provided
time and machines to identify and fix this issue.

Fix alq_getn such that it no longer uses malloc, which ensures the KPI is safe
to use in all contexts. This change allows the buffer to develop a "hole" at the
end when a wrap occurs, which should significantly improve performance in
situations where the buffer is wrapping frequently. Testing is required.

Before calling vflush(FORCECLOSE) mark file system as unmounted so the
following vnops will fail. This is very important, because without this change
vnode could be reclaimed at any point, even if we increased usecount. The only
way to ensure that vnode won't be reclaimed was to lock it, which would be very
hard to do in ZFS without changing a lot of code. With this change simply
increasing usecount is enough to be sure vnode won't be reclaimed from under
us. To be precise it can still be reclaimed but we won't be able to see it,
because every try to enter ZFS through VFS will result in EIO.

The only function that cannot return EIO, because it is needed for vflush() is
zfs_root(). Introduce ZFS_ENTER_NOERROR() macro that only locks
z_teardown_lock and never returns EIO.

Align Tx/Rx descriptors on 32 bytes boundary instead of PAGE_SIZE.
Also align setup descriptor on 32 bytes boundary. Tx buffer have no
alignment limitation so create dmamap without alignment
restriction[1]. Rx buffer still seems to require 4 bytes alignment
limitation but we can simply use MCLBYTES for size to map the
buffer instead of TULIP_DATA_PER_DESC as the buffer is allocated
with m_getcl(9).
de(4) supports up to TULIP_MAX_TXSEG segments for Tx buffers,
increase maximum dma segment size to TULIP_MAX_TXSEG * MCLBYTES.
While I'm here remove TULIP_DATA_PER_DESC as it is not used anymore.

This should fix de(4) breakage introduced after r176206.

Make SCS work in 8-bit mode.

This means we can finally do things like VT100 box drawing when using
Syscons (8-bit characters). As far as I know, the only remaining issue
is the absense of proper escape sequences for special keyboard
characters (cursor, F1 to F12, etc) and xterm emulation should be ready
for general use.

Enabling xterm would have the following advantages:

- Easier possible migration to Unicode. cons25 termcap entries are very
  8-bit centric. They use things like CP437 characters for box drawing,
  etc.

- Better support for SSH'ing to other operating systems/devices. Most
  switches use VT100-style admin interfaces.

- Reduced bandwidth, because applications can now use things like
  scrolling regions.

- You can finally use applications like dtach(1) on both the console and
  inside an xterm.

I noticed a small inconsistency in delete and insert line between xterm

This behaviour seems to be VT100-like. Confirmation:

MFC rev. 197462:
Do not call BUS_DRIVER_ADDED() for detached buses (attach failed) on
driver load. This fixes crash on atapicam module load on systems, where
some ata channels (usually ata1) was probed, but failed to attach.

Remove constraint, requiring request data to fulfill controller's
alignment requirements. It is busdma task, to manage proper alignment by
loading data to bounce buffers.

Reject some VESA graphics modes if the controller does not have enough
memory to support them.  Some adapters have expansible memory slots but
video mode table is static.  In this case, unusable modes may be reported.

Switch to fletcher4 as the default checksum algorithm. Fletcher2 was proven to
be a bit weak and OpenSolaris also switched to fletcher4.

- Use x86bios_offset() instead of BIOS_PADDRTOVADDR() macro.[1]
- Clear all registers before calling real mode interrupt handlers as we did
for dpms and vesa and re-enable the function as it should be fixed by this.
- Tidy up register access.  For example, when we call INT 0x15, AH=0xc0,
we used to initialize AX=0xc000 to clear AL at the same time but it is
very confusing.  We don't have to do this any more because we are explicitly
clearing all registers now.
- Check size of system configuration table although it is almost always 8.
This is to make sure we are not reading some random low physical memory.
Hopefully it is just zero in that case. :-)
- Fix some style nits and add more comments.

- According to Linux, the ALi M5451 can do 31-bit DMA instead of just
  30-bit like the reset of the controllers supported by this driver.
  Actually ALi M5451 can be setup up to generate 32-bit addresses by
  setting the 31st bit via the accompanying ISA bridge, which allows
  it to work in sparc64 machines whose IOMMU require at least 32-bit
  DMA. Even though other architectures would also benefit from 32-bit
  DMA, enabling this bit is limited to sparc64 as bus_dma(9) doesn't
  generally guarantee that a low address of BUS_SPACE_MAXADDR_32BIT
  results in a buffer in the 32-bit range.
- According to Tatsuo YOKOGAWA's ali(4), the the DMA transfer size of
  ALi M5451 is fixed to 64k and in fact using the default size of 4k
  causes the chip to overrun the mapping, triggering uncorrectable
  DMA errors on sparc64.
- The 4DWAVE DX and NX require the recording buffer to be 8-byte
  aligned so adjust the bus_dma_tag_create(9) accordingly.
- Unlike the rest of the controllers supported by this driver, the
  ALi M5451 only has 32 hardware channels instead of 64 so limit the
  loop in tr_intr() accordingly. [1]
