When aggregating TRIM segments, move the new one to the list end.
New segment at the list head may block all TRIM requests until txg of that
segment can be processed. On my random I/O tests this change reduce peak
TRIM list length from 650 to 450 segments. Hopefully it should reduce TRIM
burstiness when list processing is unblocked.

cxgb: replace r273280 with a more comprehensive fix.
Poll for link state when the link is down, even for interrupt capable
PHYs.
Allow PHYs to report a dubious "partial" link. If this state is seen 3
consecutive times (each check is ~1s apart) then reset the PHY. This is
a workaround for a situation where repeatedly toggling the link from the
peer gets the AEL2005 PHY into a state where it never establishes a PCS
block lock even when everything is in order.

Add LBA as secondary sort key for synchronous I/O requests.
On FreeBSD gethrtime() implemented via getnanouptime(), that has 1ms (1/hz)
precision. It makes primary sort key (timestamp) collision very possible.
In such situations sorting by secondary key of LBA is much more reasonable
then by totally meaningless zio pointer value.
With this change on multi-threaded synchronous ZVOL read I've measured 10%
throughput increase and average latency reduction.

Use .MAKE.LEVEL being defined as a bootstrap aid when providing
fallback targets to build the aic generated files. fmake doesn't like
the current construct, and since it doesn't have .MAKE.LEVEL, just
don't provide the fallback targets for fmake. This gives a little
extra compatibility to old systems trying to build new kernels at
almost no cost to the current code.

Fix calculation of requester for PCI device behind PCIe/PCI bridge.
In my case on the test machine, I have hierarchy of
pcib2 (PCIe port on host bridge with PCIe capability) -> pci2 ->
pcib3 (ITE PCIe/PCI bridge) -> pci3 -> em1
The device to check PCIe capability is pcib2 and not pcib3, as it is
currently done in the code. Also, in case of the bridge, we shall
step to pcib2 for the loop iteration, since pcib3 does not carry PCIe
capability info and would force wrong recalculation of rid.
Also change the returned requester to the PCIe bus which provides port
for the bridge. This only results in changing
hw.busdma.pciX.X.X.X.bounce tunable to force identity-mapped context
for the device.

Garbage collect m_copymdata(), an mbuf utility routine introduced
in FreeBSD 7 that has not been used since. It contains a number
of unresolved bugs including an inverted bcopy() and incorrect
handling of read-only mbufs using internal storage. Removing this
unused code is substantially essier than fixing it in order to
update it to the coming mbuf world order -- but it can always be
restored from revision history if it turns out to prove useful for
future work.

Restore Ethernet-within-IP Encapsulation support that was broken after
r273087. Move all checks from gif_output() into gif_transmit(). Previously
they were checked always, because if_start always called gif_output.
Now gif_transmit() can be called directly from if_bridge() code and we need
do checks here.

* Deal with ARCNET L2 multicast mapping for IPv6 the same way as in IPv4:
handle it in arc_output() instead of nd6_storelladdr().
* Remove IFT_ARCNET check from arpresolve() since arc_output() does not
use arpresolve() to handle broadcast/multicast. This check was there
since r84931. It looks like it was not used since r89099 (initial
import of Arcnet support where multicast is handled separately).
* Remove IFT_IEEE1394 case from nd6_storelladdr() since firewire_output()
calles nd6_storelladdr() for unicast addresses only.
* Remove IFT_ARCNET case from nd6_storelladdr() since arc_output() now
handles multicast by itself.
As a result, we have the following pattern: all non-ethernet-style
media have their own multicast map handling inside their appropriate
routines. On the other hand, arpresolve() (and nd6_storelladdr()) which
meant to be 'generic' ones de-facto handles ethernet-only multicast maps.

Remove a 'This is dumb' comment that has been incorrect for at least a

Retain another, related, and also outdated comment, but with a caveat
that it is partially stale. Do not, for now, address the problem that
it raises (that only EXT_CLUSTER external storage is considered
writable, regardless of the results of M_WRITABLE() on the mbuf).

Please note that these libraries are *experimental* at this stage, so
the main Makefile is not yet connected to the build.
Since I didn't want to needlessly edit BSD.usr.dist, you will also have

Change the default method for device_quiesce() to return 0 instead of

devclass_quiesce_driver() stops iterating over drivers as soon as it
