MFC support for PCI Alternate RID Interpretation. ARI is an optional PCIe
feature that allows PCI devices to present up to 256 functions on a bus.
This is effectively a prerequisite for PCI SR-IOV support.

Re-implement the DMAR I/O MMU code in terms of PCI RIDs
Under the hood the VT-d spec is really implemented in terms of
PCI RIDs instead of bus/slot/function, even though the spec makes
pains to convert back to bus/slot/function in examples. However
working with bus/slot/function is not correct when PCI ARI is
in use, so convert to using RIDs in most cases. bus/slot/function
will only be used when reporting errors to a user.

r264011:
Add support for PCIe ARI
PCIe Alternate RID Interpretation (ARI) is an optional feature that
allows devices to have up to 256 different functions. It is
implemented by always setting the PCI slot number to 0 and
re-purposing the 5 bits used to encode the slot number to instead
contain the function number. Combined with the original 3 bits
allocated for the function number, this allows for 256 functions.
This is enabled by default, but it's expected to be a no-op on currently
supported hardware. It's a prerequisite for supporting PCI SR-IOV, and
I want the ARI support to go in early to help shake out any bugs in it.
ARI can be disabled by setting the tunable hw.pci.enable_ari=0.

- Add the dts include directory to the -I list when doing arm builds.
- Invoke make_dtb with MACHINE defined for cross building friendliness.

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.

portion of r270063.

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

For LUNs without these IDs VMWare will use traditional copy operations.

Be more flexible about which compatible strings to accept. This brings up
the PCI Express bus on the RB800 using the firmware device tree.
Rename the "bare" platform "mpc85xx", which is what it actually is, and
add actual platform probing based on PVR.
Use common OFW root code to set up fdtbus. This is an almost purely
negative diff that should improve reliability somewhat. There should be
no differences in behavior -- please report any that crop up. This has been
tested on ARM and PPC systems.
Make sure to get the right node when looking up #interrupt-cells.
dd mrsas(4) driver from LSI official support of newer MegaRAID SAS
cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.
mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).
It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).
Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.
Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.

Bring in the mpr(4) driver for LSI's MPT3 12Gb SAS controllers.
This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.
Some notes about this driver:
o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
this driver.
o WarpDrive functionality has been removed, since it isn't supported in
the 12Gb driver interface.
o The Scatter/Gather list handling code is significantly different between
the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather
lists.
Thanks to LSI for developing and testing this driver for FreeBSD.

Import USB RNDIS driver to FreeBSD from OpenBSD.
Useful for so-called USB tethering.
- Imported code from OpenBSD
- Adapted code to FreeBSD
- Removed some unused functions
- Fixed some buffer encoding and decoding issues
- Optimised data transport path a bit, by sending multiple packets at a time
- Increased receive buffer to 16K

Import the axge(4) driver for the ASIX AX88178A and AX88179 USB Ethernet
adapters. Both devices support Gigabit Ethernet and USB 2.0, and the AX88179
supports USB 3.0.
MFC r258617 (by lwhsu):
Also note to add xhci(4) to kernel configuration to utilize USB 3.0

In r260111, in sys/conf/files, I disabled warning about unused functions
for the wrong mcg.c, the one in ofed/drivers/infiniband/hw/mlx4.
Disable the warning for ofed/drivers/net/mlx4/mcg.c instead.
