* Introduce TX DMA setup/teardown methods, mirroring what's done in
the RX path.
Although the TX DMA descriptor is setup via ath_desc_alloc() /

- 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.
- iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the
works and will follow soon.
Build-tested with make universe.
30s overview
============
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

There's some TX path TDMA code in if_ath_tx.c which should be migrated
out, but first I should likely try and verify/fix/repair the TDMA support
in 9.x and -HEAD.
* migrate the rx processing out into if_ath_rx.c
* migrate the TSF functions into if_ath_tsf.h, as inlines
This is in prepration for supporting the EDMA RX routines, required to
support the AR93xx series NICs.
TODO:
* ath_start() shouldn't be private, but it's called as part of
the RX path. I should likely migrate ath_rx_tasklet() back into
if_ath.c and then return this to be 'static'. The RX code really
shouldn't need to see TX routines (and vice versa.)
* ath_beacon_* should be in if_ath_beacon.[ch].
* ath_tdma_* should be in if_ath_tdma.[ch] ...

* 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.
Tested on: AP93 (AR7240) reference design

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

Supports all single-layer RAID levels. Dual-layer RAID levels except
RAID10 are not supported now because of GEOM RAID design limitations.

The 'make depend' rules have to use custom -I paths for the special compat

This option will pull in the couple of files that are shared with dtrace,
