o convert to if_transmit;
o use rmlock to protect access to gif_softc;
o use sx lock to protect from concurrent ioctls;
o remove a lot of unneeded and duplicated code;
o remove cached route support (it won't work with concurrent io);
o style fixes.

- Merge the amd64 and i386 identcpu.c into a single x86 implementation.
Change the PF hash from Jenkins to Murmur3. In forwarding tests

Enhancements related to compiling FDT data...
- Use proper include path for dtc as well as cpp.
- Call cpp with -P to avoid printing line markings.
- Allow FDT_DTS_FILE to be a list, either in the makedtb target, or in a
kernel config file.
- Add the dts include directory to the -I list when doing arm builds.
- Invoke make_dtb with MACHINE defined for cross building friendliness.
- Allow the make_dtb script to work outside of a "make buildkernel"
context by setting MACHINE from uname -m if it's not set already.
- Use sh -c '...' to launch the dtb build scripts with env prepended,
otherwise it tries to treat the env var stuff as a script file name.

The flowdirector feature shares on-chip memory with other things
such as the RX buffers. In theory it should be configured in a way
that doesn't interfere with the rest of operation. In practice,
the RX buffer calculation didn't take the flow-director allocation
into account and there'd be overlap. This lead to various garbage
frames being received containing what looks like internal NIC state.
What _I_ saw was traffic ending up in the wrong RX queues.
If I was doing a UDP traffic test with only one NIC ring receiving
traffic, everything is fine. If I fired up a second UDP stream
which came in on another ring, there'd be a few percent of traffic
from both rings ending up in the wrong ring. Ie, the RSS hash would
indicate it was supposed to come in ring X, but it'd come in ring Y.
However, when the allocation was fixed up, the developers at Verisign
still saw traffic stalls.
The flowdirector feature ends up fiddling with the NIC to do various
attempts at load balancing connections by populating flow table rules
based on sampled traffic. It's likely that all of that has to be
carefully reviewed and made less "magic".
So for now the flow director feature is disabled (which fixes both
what I was seeing and what they were seeing) until it's all much
more debugged and verified.
Tested:
* (me) 82599EB 2x10G NIC, RSS UDP testing.
* (verisign) not sure on the NIC (but likely 82599), 100k-200k/sec TCP
transaction tests.

r269601 (nwhitehorn):
Add a simple unaccelerated vt(4) framebuffer driver for Sun
framebuffers handled by creator(4) (Sun Creator 3D, Elite 3D, etc.).
This provides vt(4) consoles on all devices currently supported by
syscons on sparc64. The driver should also be easily adaptable to
support newer Sun framebuffers such as the XVR-500 and higher.
Many thanks to dumbbell@ (Jean-Sebastien Pedron) for testing this

cxgbe(4): Remove stray if_up from the code that creates the tracing ifnet.
r266757:
cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards.
Netmap gets its own hardware-assisted virtual interface and won't take
over or disrupt the "normal" interface in any way. You can use both
simultaneously.
For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface
(note the 'n' prefix) in the hardware to accompany each cxl<N>
interface. These two ifnet's per port share the same wire but really
are separate interfaces in the hardware and software. Each gets its own
L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You
should run netmap on the 'n' interfaces only, that's what they are for.
With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port
of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now.
Single port receive is at 33Mpps but this is very much a work in
progress. I expect it to be closer to 40Mpps once done. In any case
the current effort can already saturate multiple 10G ports of a T5 card
at the smallest legal packet size. T4 gear is totally untested.

Remove aicasm as a build dependency. It made sense when the ahc and ahd
drivers and their firmware were under active development, but those days
have passed. The firmware now exists in pre-compiled form, no longer
dependent on it's sources or on aicasm. If you wish to rebuild the
firmware from source, the glue still exists under the 'make firmware'
target in sys/modules/aic7xxx.
This also fixes the problem introduced with r257777 et al with building
kernels the old fashioned way in sys/$arch/compile/$CONFIG when the
ahc/ahd drivers were included.
Changes to how the aicasm tool is built. This series of changes results
in the aicasm tool being built as part of the tools stages of world and
kernel builds.
Most of these changes will ultimately be undone when r260401 is MFC'd,
but it will leave in place the new kernel-build-tool machinery (KTMAKE
stuff) in case a new special kernel tool ever comes along.
Set ofwbus and simplebus to attach during BUS_PASS_BUS.

Attach arm generic interrupt and timer drivers in the middle of
BUS_PASS_INTERRUPT and BUS_PASS_TIMER, respectively.
Add an arm option, ARM_DEVICE_MULTIPASS, used to opt-in to multi-pass
device attachment on arm platforms. If this is defined, nexus attaches
early in BUS_PASS_BUS, and other busses and devices attach later, in the
pass number they are set up for. Without it defined, nexus attaches in
BUS_PASS_DEFAULT and thus so does everything else, which is status quo.
Merge the NFSv4.1 server code in projects/nfsv4.1-server over

Add support for VMWare dialect of EXTENDED COPY command, aka VAAI Clone.
This allows to clone VMs and move them between LUNs inside one storage
host without generating extra network traffic to the initiator and back,
and without being limited by network bandwidth.
LUNs participating in copy operation should have UNIQUE NAA or EUI IDs set.
For LUNs without these IDs VMWare will use traditional copy operations.
Beware: the above LUN IDs explicitly set to values non-unique from the VM
cluster point of view may cause data corruption if wrong LUN is addressed!
