sleepable context for net80211 driver callbacks. This removes the need for USB
and firmware based drivers to roll their own code to defer the chip programming
for state changes, scan requests, channel changes and mcast/promisc updates.
When a driver callback completes the hardware state is now guaranteed to have
been updated and is in sync with net80211 layer.
This nukes around 1300 lines of code from the wireless device drivers making
them more readable and less race prone.
The net80211 layer has been updated as follows
- all state/channel changes are serialised on the taskqueue.
- ieee80211_new_state() always queues and can now be called from any context
- scanning runs from a single taskq function and executes to completion. driver
callbacks are synchronous so the channel, phy mode and rx filters are
guaranteed to be set in hardware before probe request frames are
transmitted.

- Probe supported sleep states from acpi_attach() just once and do not
call AcpiGetSleepTypeData() again. It is redundant because
AcpiEnterSleepStatePrep() does it any way.
- Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure
NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions.
- Do not set unsupported sleep states as default button/switch events.
If the default sleep state is not supported, just set it as UNKNOWN/NONE.
- Do not allow sleep state change if the system is not fully up and running.
This should prevent entering S5 state multiple times, which causes strange
behaviours later.
- Make sleep states case-insensitive when they are used with sysctl(8).
For example,
sysctl hw.acpi.lid_switch_state=s1
sysctl hw.acpi.sleep_button_state=none
are now legal and equivalent to the uppercase ones.
Feature is controlled by hint.ata.X.pm_level tunable:
0 - PM disabled, old behaviour, default.
1 - device is allowed to initiate PM state change, host is passive.
2 - host initiates PARTIAL state transition every time port is idle.
3 - host initiates SLUMBER state transition every time port is idle.
PARTIAL state has up to 100us (50us for me) wakeup latency, but for my
ICH8M saves 0.5W of power per drive. SLUMBER state has up to 10ms (3.5ms
for me) wakeup latency, but saves 0.8W of power.
Modes 2 and 3 are implemented only for AHCI driver now.
Interface power management is incompatible with device presence detection
(host receives no signal from drive, so unable to monitor it), so later is
disabled when PM is used.

This change adds (possibly redundant) early check for invalid
state input parameter (including S0). Handling of S5 request
is reduced to simply calling shutdown_nice(). As a result
control flow of acpi_EnterSleepState is somewhat simplified
and resume/backout half of the function is not executed
for S5 (soft poweroff) request and invalid state requests.
Note: it seems that shutdown_nice may act as nop when initproc
is already initialized (to grab pid of 1), but init process is in
"pre-natal" state.

- For PCI Express devices:
1) Adjust max read request size to 4Kbytes
2) Turn on FIFO_LONG_BURST in RDMA during bge_blockinit()
Though 1) does not seem to have much to do with the poor TX performance

It seems I didn't fix this issue before committing teken to the tree. My
initial idea was to somehow add an error mechanism to instruct the video
driver author to increase T_NUMCOL when using very big terminals. It
turns out we have platforms where we have gigantic consoles on systems
like the Apple PowerMac G5, which means we crash there right now.

C-NET(PC) has a cfe at location 1 that has both an odd irq mask (it
matches pc98 machines, so maybe it was a flag for pc98 operation) as
well as a memory map. Since this driver doesn't know how to cope, we
start with cfe2, which is purely an I/O space mapped and that seems to
make it work. I say 'seems' here, because the card I have doesn't
seem to have the right dongle for full testing...

(2) When contrainting a resource request for a 'subtractive' bridge,

arbitrarily pick the range just above the hole to allocate from.

o Header file cleanup.
o bus_dma(9) conversion.
- Removed all consumers of vtophys(9) and converted to use
bus_dma(9).
- Typhoon2 functional specification says the controller supports
64bit DMA addressing. However all Typhoon controllers are known
to lack of DAC support so 64bit DMA support was disabled.
- The hardware can't handle more 16 fragmented Tx DMA segments so
teach txp(4) to collapse these segments to be less than 16.
- Added Rx buffer alignment requirements(4 bytes alignment) and
implemented fixup code to align receive frame. Previously
txp(4) always copied Rx frame to align it on 2 byte boundary
but its copy overhead is much higher than unaligned access on
i386/amd64. Alignment fixup code is now applied only for
strict-alignment architectures. With this change i386 and
amd64 will get instant Rx performance boost. Typhoon2 datasheet
mentions a command that pads arbitrary bytes in Rx buffer but
that command does not work.
- Nuked pointer trick in descriptor ring. This does not work on
sparc64 and replaced it with bcopy. Alternatively txp(4) can
embed a 32 bits index value into the descriptor and compute
real buffer address but it may make code complicated.
- Added endianness support code in various Tx/Rx/command/response
descriptor access. With this change txp(4) should work on all
architectures.
o Added comments for known firmware bugs(Tx checksum offloading,
TSO, VLAN stripping and Rx buffer padding control).
o Prefer faster memory space register access to I/O space access.
Added fall-back mechanism to use alternative I/O space access.
The hardware supports both memory and I/O mapped access. Users
can still force to use old I/O space access by setting
hw.txp.prefer_iomap tunable to 1 in /boot/loader.conf.
o Added experimental suspend/resume methods.
o Nuke error prone Rx buffer handling code and implemented local
buffer management with TAILQ. Be definition the controller can't
pass the last received frame to host if no Rx free buffers are
available to use as head and tail pointer of Rx descriptor ring
can't have the same value. In that case the Rx buffer pointer in
Rx buffer ring still holds a valid buffer and txp_rxbuf_reclaim()
can't fill Rx buffers as the first buffer is still valid. Instead
of relying on the value of Rx buffer ring, introduce local buffer
management code to handle empty buffer situation. This should fix
a long standing bug which completely hangs the controller under
high network load. I could easily trigger the issue by sending 64
bytes UDP frames with netperf. I have no idea how this bugs was
not fixed for a long time.
o Converted ithread interrupt handler to filter based one.
o Rearranged txp_detach routine such that it's now used for general
clean-up routine.
o Show sleep image version on device attach time. This will help
to know what action should be taken depending on sleep image
version. The version information in datasheet was wrong for newer
NV images so I followed Linux which seems to correctly extract
version numbers from response descriptors.
o Firmware image is no longer downloaded in device attach time. Now
it is reloaded whenever if_init is invoked. This is to ensure
correct operation of hardware when something goes wrong.
Previously the controller always run without regard to running
state of firmware. This change will add additional controller
initialization time but it give more robust operation as txp(4)
always start off from a known state. The controller is put into
sleep state until administrator explicitly up the interface.
o As firmware is loaded in if_init handler, it's now possible to
implement real watchdog timeout handler. When watchdog timer is
expired, full-reset the controller and initialize the hardware
again as most other drivers do. While I'm here use our own timer
for watchdog instead of using if_watchdog/if_timer interface.
o Instead of masking specific interrupts with TXP_IMR register,
program TXP_IER register with the interrupts to be raised and
use TXP_IMR to toggle interrupt generation.
o Implemented txp_wait() to wait a specific state of a controller.
o Separate boot related code from txp_download_fw() and name it
txp_boot() to handle boot process.
o Added bus_barrier(9) to host to ARM communication.
o Added endianness to all typhoon command processing. The ARM93C
always expects little-endian format of command/data.
o Removed __STRICT_ALIGNMENT which is not valid on FreeBSD.
__NO_STRICT_ALIGNMENT is provided for that purpose on FreeBSD.
Previously __STRICT_ALIGNMENT was unconditionally defined for
all architectures.
o Rewrote SIOCSIFCAP ioctl handler such that each capability can be
controlled by ifconfig(8). Note, disabling VLAN hardware tagging
has no effect due to the bug of firmware.
o Don't send TXP_CMD_CLEAR_STATISTICS to clear MAC statistics in
txp_tick(). The command is not atomic. Instead, just read the
statistics and reflect saved statistics to the statistics.
dev.txp.%d.stats sysctl node provides detailed MAC statistics.
This also reduces a lot of waste of CPU cycles as processing a
command ring takes a very long time on ARM93C. Note, Rx
multicast and broadcast statistics does not seem to right. It
might be another bug of firmware.
o Implemented link state change handling in txp_tick(). Now sending
packets is allowed only after establishing a valid link. Also
invoke link state change notification whenever its state is
changed so pseudo drivers like lagg(4) that relies on link state
can work with failover or link aggregation without hacks.
if_baudrate is updated to resolved speed so SNMP agents can get
correct bandwidth parameters.
o Overhauled Tx routine such that it now honors number of allowable
DMA segments and checks for 4 free descriptors before trying to
send a frame. A frame may require 4 descriptors(1 frame
descriptor, 1 or more frame descriptors, 1 TSO option descriptor,
one free descriptor to prevent descriptor wrap-around) at least
so it's necessary to check available free descriptors prior to
setting up DMA operation.
o Added a sysctl variable dev.txp.%d.process_limit to control
how many received frames should be served in Rx handler. Valid
ranges are 16 to 128(default 64) in unit of frames.
o Added ALTQ(4) support.
o Added missing IFCAP_VLAN_HWCSUM as txp(4) can offload checksum
calculation as well as VLAN tag insertion/stripping.
o Fixed media header length for VLAN.
o Don't set if_mtu in device attach, it's already set in
ether_ifattach().
o Enabled MWI.
o Fixed module unload panic when bpf listeners are active.
o Rearranged ethernet address programming logic such that it works
on strict-alignment architectures.
o Removed unused member variables in softc.
o Added support for WOL.
o Removed now unused TXP_PCI_LOMEM/TXP_PCI_LOIO.
o Added wakeup command TXP_BOOTCMD_WAKEUP definition.
o Added a new firmware version query command, TXP_CMD_READ_VERSION.
o Removed volatile keyword in softc as bus_dmamap_sync(9) should
take care of this.
o Removed embedded union trick of a structure used to to access
a pointer on LP64 systems.
o Added a few TSO related definitions for struct txp_tcpseg_desc.
However TSO is not used at all due to the limitation of hardware.
o Redefined PKT_MAX_PKTLEN to theoretical maximum size of a frame.
o Switched from bus_space_{read|write}_4 to bus_{read|write}_4.
o Added a new macro TXP_DESC_INC to compute next descriptor index.

filesystem supports additional operations using shared vnode locks.
Currently this is used to enable shared locks for open() and close() of
read-only file descriptors.
- When an ISOPEN namei() request is performed with LOCKSHARED, use a
shared vnode lock for the leaf vnode only if the mount point has the
extended shared flag set.
- Set LOCKSHARED in vn_open_cred() for requests that specify O_RDONLY but
not O_CREAT.
- Use a shared vnode lock around VOP_CLOSE() if the file was opened with
O_RDONLY and the mountpoint has the extended shared flag set.
- Adjust md(4) to upgrade the vnode lock on the vnode it gets back from
vn_open() since it now may only have a shared vnode lock.
- Don't enable shared vnode locks on FIFO vnodes in ZFS and UFS since
FIFO's require exclusive vnode locks for their open() and close()
routines. (My recent MPSAFE patches for UDF and cd9660 already included
this change.)
- Enable extended shared operations on UFS, cd9660, and UDF.
