usermode, using shared page. The structures and functions have vdso
prefix, to indicate the intended location of the code in some future.
The versioned per-algorithm data is exported in the format of struct
vdso_timehands, which mostly repeats the content of in-kernel struct
timehands. Usermode reading of the structure can be lockless.
Compatibility export for 32bit processes on 64bit host is also
provided. Kernel also provides usermode with indication about
currently used timecounter, so that libc can fall back to syscall if
configured timecounter is unknown to usermode code.
The shared data updates are initiated both from the tc_windup(), where
a fast task is queued to do the update, and from sysctl handlers which
change timecounter. A manual override switch
kern.timecounter.fast_gettime allows to turn off the mechanism.
Only x86 architectures export the real algorithm data, and there, only
for tsc timecounter. HPET counters page could be exported as well, but
I prefer to not further glue the kernel and libc ABI there until
proper vdso-based solution is developed.
Minimal stubs neccessary for non-x86 architectures to still compile
are provided.

- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
These are available as t3_tom and t4_tom modules that augment cxgb(4)
and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as
usual with or without these extra features.

============
What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE
Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe
Which connections are offloaded? Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe

List of these flags can be modified with CAM_DEBUG_COMPILE kernel option.
CAMDEBUG kernel option still enables all possible debug, if not overriden.
Additional 50KB of kernel size is a good price for the ability to debug

debugging can be compiled out by setting CAM_DEBUG_COMPILE option to 0.

There's some TX path TDMA code in if_ath_tx.c which should be migrated

* Add in the AR724x support. It probes the same as an AR8216/AR8316, so
just add in a hint to force the probe success rather than auto-detecting
it.
* Add in the missing entries from conf/files, lacking in the previous
commit.
The register values and CPU port / mirror port initialisation value was
obtained from Linux OpenWRT ag71xx_ar7240.c.
The DELAY(1000) to let things settle is my local workaround. For some
reason, PHY4 doesn't seem to probe very reliably without it. It's quite
possible that we're missing some MDIO bus initialisation code in if_arge
for the AR724x case. As I dislike DELAY() workarounds in general, it's
definitely worth trying to figure out why this is the case.

ports. This currently is a nop, but will soon be used to allow
support for multiple boards to be built into one kernel (starting with
AT91RM9200 and expanding out from there).
This is only done if the ARGE_MDIO option is included.
* Shuffle the arge MDIO bus into a separate device, that needs to be
probed early (use hint.argemdio.X.order=0)
* hint.arge.X.mdio now specifies which miiproxy to rendezvous with.
* Call MAC/MDIO bus init during MDIO attach, not arge attach.
This is done regardless:
* Shift the arge MAC and MDIO bus reset code into separate functions
and call it early during MDIO bus attach. It's required for
correct MDIO bus IO to occur on AR71xx/AR91xx devices.
* Remove the AR71xx/AR91xx centric assumption that there's only one
MDIO bus. The initial code mapped miibus0(arge0) and miibus1(arge1)
MII register operations to the MII0 (arge0) register space. The
AR724x (and later, upcoming chipsets) have two MDIO busses and
the second is very much in use.

MDIO/MII rendezvous proxy.
* Add an 'mdio' bus, which is the "IO" side of an MII bus (but by design
can be anything which implements the underlying register access API.)
* Add 'miiproxy' and 'mdioproxy', which provides a rendezvous mechanism
for MII busses to appear hanging off arbitrary busses (ie, that aren't
necessarily a traditional looking MII bus.)
MII busses can now hang off anything that implements an mdiobus.
For the AR71xx SoC, there's one MDIO bus but two MII busses. So to
properly support two or more real PHYs, this can be done:
# arge0 MDIO bus - there's no arge1 MDIO bus for AR71xx
hint.argemdio.0.at="nexus0"
hint.argemdio.0.maddr=0x19000000
hint.argemdio.0.msize=0x1000
hint.argemdio.0.order=0
# Create two mdioproxy instances
hint.mdioproxy.0.at="mdio0"
hint.mdioproxy.1.at="mdio0"
# .. and with a follow-up patch
hint.arge.0.mdio=mdioproxy0
hint.arge.1.mdio=mdioproxy0

* Do a sweep or two and add appropriate locking in mdio/mdioproxy/miiproxy.
